82884c79ae Signed Levels and Levelpacks
Add the ability for the free version of the game to allow loading levels that
use embedded custom doodads if those levels are signed.

* Uses the same signing keys as the JWT token for license registrations.
* Levels and Levelpacks can both be signed. So individual levels with embedded
  doodads can work in free versions of the game.
* Levelpacks now support embedded doodads properly: the individual levels in
  the pack don't need to embed a custom doodad, but if the doodad exists in
  the levelpack's doodads/ folder it will load from there instead - for full
  versions of the game OR when the levelpack is signed.

Signatures are computed by getting a listing of embedded assets inside the
zipfile (the assets/ folder in levels, and the doodads/ + levels/ folders
in levelpacks). Thus for individual signed levels, the level geometry and
metadata may be changed without breaking the signature but if custom doodads
are changed the signature will break.

The doodle-admin command adds subcommands to `sign-level` and `verify-level`
to manage signatures on levels and levelpacks.

When using the `doodad levelpack create` command, any custom doodads the
levels mention that are found in your profile directory get embedded into
the zipfile by default (with --doodads custom).

af6b8625d6 Flood Tool, Survival Mode for Azulian Tag
New features:
* Flood Tool for the editor. It replaces pixels of one color with another,
  contiguously. Has limits on how far from the original pixel it will color,
  to avoid infinite loops in case the user clicked on wide open void. The
  limit when clicking an existing color is 1200px or only a 600px limit if
  clicking into the void.
* Cheat code: 'master key' to play locked Story Mode levels.

Level GameRules feature added:
* A new tab in the Level Properties dialog
* Difficulty has been moved to this tab
* Survival Mode: for silver high score, longest time alive is better than
  fastest time, for Azulian Tag maps. Gold high score is still based on
  fastest time - find the hidden level exit without dying!

Tweaks to the Azulians' jump heights:
* Blue Azulian:  12 -> 14
* Red Azulian:   14 -> 18
* White Azulian: 16 -> 20

Bugs fixed:
* When editing your Palette to rename a color or add a new color, it wasn't
  possible to draw with that color until the editor was completely unloaded
  and reloaded; this is now fixed.
* Minor bugfix in Difficulty.String() for Peaceful (-1) difficulty to avoid
  a negative array index.
* Try and prevent user giving the same name to multiple swatches on their
  palette. Replacing the whole palette can let duplication through still.

48e18da511 Centralize cheats, detect cheated player character
* If the player runs the PlayAsBird cheat they shouldn't be able to win
  a high score on a level, so at level startup it detects whether the
  DefaultPlayerCharacterDoodad has changed from default on a level that
  doesn't use the Start Flag to set a specific doodad - and immediately
  marks the session as cheated

9a51ac39f9 Spit and polish
* New doodad: Invisible Warp Door
* All warp doors require the player to be grounded (if affected by
  gravity) to open them. No jumping or falling thru and opening
  a warp door mid-air!
* Title Screen now randomly selects from a couple of levels.
* Title Screen: if it fails to load a level it sets up a basic
  blank level with a wallpaper instead.
* New developer shell command: titlescreen <level>
  Opens the MainScene with a custom user level as the background.
* Add Auto-save to the Editor to save your drawing every 5 minutes
* Add a MenuBar to the Play Scene for easier navigation to other
  features of the game.
* Doodad JS API: time.Since() now available.

672ee9641a Savegame and High Scores
* Adds pkg/savegame to store user progress thru Level Packs.
* The savegame.json is mildly tamper resistant by including a checksum
  along with the JSON body.
* The checksum combines the JSON string + an app secret (in savegame.go)
  + user specific entropy (stored in their settings.json). If the user
  modifies their save file and the checksum becomes invalid the game
  will not load the save file, acting like it didn't exist, resetting
  all their high scores.

Updates to the Story Mode window:

* On the LevelPacks list: shows e.g. "[completed 0 of 3 levels]" showing
  a user's progress thru the level pack.
* Below the levels on the Detail screen:
  * Shows an indicator whether the level is completed or not.
  * Shows high scores (fastest times beating the level)
  * Shows a padlock icon if levels are locked and the player hasn't
    reached them yet. Pops up an Alert modal if a locked level is
    clicked on.

Scoring is based around your fastest time elapsed to finish the level.

* Perfect Time (gold coin): player has not died during the level.
* Best Time (silver coin): player has continued from a checkpoint.

In-game an elapsed timer is shown in the top left corner along with the
gold or silver coin indicating if your run has been Perfect.

If the user enters any Cheat Codes during gameplay they are not eligible
to win a high score, but the level will still be marked as completed.
The icon next to the in-game timer disappears when a cheat code has been
entered.

fa5f303dad Bugfix: embedded levelpacks from bindata 2021-12-30 18:39:11 -08:00
d16a8657aa Window Icon, UI Polish
* SDL2 builds of the game now set their app window icon.
* Create/Edit Level window is updated to show a tabbed UI to create a
  new Level or a new Doodad. The dedicated main menu button to create a
  new doodad (which immediately prompted for its size) is replaced by
  this new tab's UI.
* Edit Drawing/Play Level window is more responsive to smaller screen
  sizes by drawing fewer columns of filenames.
* Bugfix: the Alert and Confirm modals always re-center themselves on
  screen, especially to adapt between Portrait or Landscape mode on a
  mobile device.

6d3ffcd98c Finalize basic functionality for Level Packs
* The "Story Mode" button on the MainScene opens the levelpacks window.
* Levelpacks from all places are shown (built-in and user files), basic
  level picker works.
* When playing a level out of a levelpack: the PlayScene gets the file
  data from the zipfile and plays it OK.
* When a levelpack level is solved, the "Next Level" button appears on
  the success modal and hitting Return will advance to the next level in
  the pack. The final level doesn't show this button.
* The user can edit levelpack levels! Clicking the "Edit" button on the
  Play Mode moves the loaded level over to the EditScene and the user
  could save it to disk or edit/playtest it perfectly OK! The link to
  the levelpack is lost upon opening in the editor, so the "Next Level"
  victory button doesn't appear.

678326540b WIP LevelPack UI + Landscape Mode Title Screen
The title screen is now responsive to landscape mode. If the window is
not tall enough to show all the menu buttons (~600px) it will switch to
a horizontal layout with the title on the left and buttons on the right.

WIP "Story Mode" button that brings up a Level Packs selection window.
