93623e4e8a Zipfiles as File Format for Levels and Doodads
Especially to further optimize memory for large levels, Levels and
Doodads can now read and write to a ZIP file format on disk with
chunks in external files within the zip.

Existing doodads and levels can still load as normal, and will be
converted into ZIP files on the next save:

* The Chunker.ChunkMap which used to hold ALL chunks in the main json/gz
  file, now becomes the cache of "hot chunks" loaded from ZIP. If there is
  a ZIP file, chunks not accessed recently are flushed from the ChunkMap
  to save on memory.
* During save, the ChunkMap is flushed to ZIP along with any non-loaded
  chunks from a previous zipfile. So legacy levels "just work" when
  saving, and levels loaded FROM Zip will manage their ChunkMap hot
  memory more carefully.

Memory savings observed on "Azulian Tag - Forest.level":

* Before: 1716 MB was loaded from the old level format into RAM along
  with a slow load screen.
* After: only 243 MB memory was used by the game and it loaded with
  a VERY FAST load screen.

Updates to the F3 Debug Overlay:

* "Chunks: 20 in 45 out 20 cached" shows the count of chunks inside the
  viewport (having bitmaps and textures loaded) vs. chunks outside which
  have their textures freed (but data kept), and the number of chunks
  currently hot cached in the ChunkMap.

The `doodad` tool has new commands to "touch" your existing levels
and doodads, to upgrade them to the new format (or you can simply
open and re-save them in-game):

    doodad edit-level --touch ./example.level
    doodad edit-doodad --touch ./example.doodad

The output from that and `doodad show` should say "File format: zipfile"
in the headers section.

To do:

* File attachments should also go in as ZIP files, e.g. wallpapers

d694fcc7c2 Fix climbing on the right bug + eager-render boolprop
* New boolProp to help debug memory issues: eager-render, set it to
  false and the loadscreen will not eagerload Go images for all the
  level chunks.
* Finally fix the level collision bug where the player could climb walls
  to the right.

8603c43c58 Gzip Compression for Levels and Doodads
* Levels and Doodad files will be written in gzip-compressed JSON format
* `boolProp compress-drawings false` to disable compression and save as
  classic JSON format directly
* The game can still read uncompressed JSON files

The file size savings on some built-in assets:

* Tutorial 2.level: 2.2M -> 414K (82% smaller)
* warp-door-orange.doodad: 105K -> 17K (84% smaller)

864156da53 Settings Window + Bugfix
* Added a Settings window for game options, such as enabling the
  horizontal toolbars in Edit Mode. The Settings window also has a
  Controls tab showing the gameplay buttons and keyboard shortcuts.
* The Settings window is available as a button on the home screen OR
  from the Edit->Settings menu in the EditScene.
* Bugfix: using WASD to move the player character now works better and
  is considered by the game to be identical to the arrow key inputs. Boy
  now updates his animation based on these keys, and they register as
  boolean on/off keys instead of affected by key-repeat.
* Refactor the boolProps: they are all part of usercfg now, and if you
  run e.g. "boolProp show-all-doodads true" and then cause the user
  settings to save to disk, that boolProp will be permanently enabled
  until turned off again.

d6f86487f5 Horizontal Toolbars Option for Editor Mode
On small screen sizes like the Pinephone, the toolbars in the Level
Editor are best made horizontal across the top and bottom of the screen
leaving more room for the drawing.

Enable it with a boolProp for now, and then reopen the level editor:

    boolProp horizontalToolbars true

When launching `doodle -w mobile` it will automatically enable this
option.

6af60f1128 Improve Collision Detection: More Active w/ Actors
* Improve the collision detection algorithm so that Actor OnCollide
  scripts get called more often WHILE an actor is moving, to prevent a
  fast-moving actor from zipping right through the "solid" hitbox and
  not giving the subject actor time to protest the movement.
* It's implemented by adding a `Settled` boolean to the OnCollide event
  object. When the game is testing out movement, Settled=false to give
  the actor a chance to say "I'm solid!" and have the moving party be
  stopped early.
* After all this is done, for any pair of actors still with overlapping
  hitboxes, OnCollide is called one last time with Settled=true. This is
  when the actor should run its actions (like publishing messages to
  other actors, changing state as in a trapdoor, etc.)
* The new collision detection algorithm works as follows:
  * Stage 1 is the same as before, all mobile actors are moved and
    tested against level geometry. They record their Original and New
    position during this phase.
  * Stage 2 is where we re-run that movement but ping actors being
    intersected each step of the way. We trace the steps between
    Original and New position, test OnCollide handler, and if it returns
    false we move the mobile actor to the Last Good Position along the
    trace.
  * Stage 3 we run the final OnCollide(Settled=true) to let actors run
    actions they wanted to for their collide handler, WITHOUT spamming
    those actions during Stage 2.
* This should now allow for tweaking of gravity speed and player speed
  without breaking all actor collision checking.

fd649b7ab1 Doodad CLI Tool Features; Write Lock and Hidden
* The `doodad` CLI tool got a lot of new commands:
  * `doodad show` to verbosely print details about Levels and Doodads.
  * `edit-level` and `edit-doodad` to update details about Levels and
    Doodads, such as their Title, Author, page type and size, etc.
* Doodads gain a `Hidden bool` that hides them from the palette in
  Editor Mode. The player character (Blue Azulian) is Hidden.
* Add some boolProps to the balance/ package and made a dynamic system
  to easily configure these with the in-game dev console.
  * Command: `boolProp list` returns available balance.boolProps
  * `boolProp <name>` returns the current value.
  * `boolProp <name> <true or false>` sets the value.
* The new boolProps are:
  * showAllDoodads: enable Hidden doodads on the palette UI (NOTE:
    reload the editor to take effect)
  * writeLockOverride: edit files that are write locked anyway
  * prettyJSON: pretty-format the JSON files saved by the game.
