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).

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.

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.
