3c185528f9 Implement Chunk System for Pixel Data
Starts the implementation of the chunk-based pixel storage system for
levels and drawings.

Previously the levels had a Pixels structure which was just an array of
X,Y and palette index triplets. The new chunk system divides the map up
into square chunks, and lets each chunk manage its own memory layout.

The "MapAccessor" layout is implemented first which is a map of X,Y
coordinates to their Swatches (pointer to an index of the palette). When
serialized the MapAccessor maps the "X,Y": "index" similarly to the old
Pixels array.

The object hierarchy for the chunk system is like:

* Chunker: the manager of the chunks who keeps track of the ChunkSize
  and a map of "chunk coordinates" to the chunk in charge of it.
  * Chunk: a part of the drawing ChunkSize length square. A chunk has a
    Type (of how it stores its data, 0 being a map[Point]Swatch and 1
    being a [][]Swatch 2D array), and the chunk has an Accessor which
    implements the underlying type.
    * Accessor: an interface for a Chunk to provide access to its
      pixels.
      * MapAccessor: a "sparse map" of coordinates to their Swatches.
      * GridAccessor: TBD, will be a "dense" 2D grid of Swatches.

The JSON files are loaded in two passes:

1. The chunks only load their swatch indexes from disk.
2. With the palette also loaded, the chunks are "inflated" and linked
   to their swatch pointers.

Misc changes:

* The `level.Canvas` UI widget switches from the old Grid data type to
  being able to directly use a `level.Chunker`
* The Chunker is a shared data type between the on-disk level format and
  the actual renderer (level.Canvas), so saving the level is easy
  because you can just pull the Chunker out from the canvas.
* ChunkSize is stored inside the level file and the default value is at
  balance/numbers.go: 1000

5956863996 Menu Toolbar for Editor + Shell Prompts + Theme
* Added a "menu toolbar" to the top of the Edit Mode with useful buttons
  that work: New Level, New Doodad (same thing), Save, Save as, Open.
* Added ability for the dev console to prompt the user for a question,
  which opens the console automatically. "Save", "Save as" and "Load"
  ask for their filenames this way.
* Started groundwork for theming the app. The palette window is a light
  brown with an orange title bar, the Menu Toolbar has a black
  background, etc.
* Added support for multiple fonts instead of just monospace. DejaVu
  Sans (normal and bold) are used now for most labels and window titles,
  respectively. The dev console uses DejaVu Sans Mono as before.
* Update ui.Label to accept PadX and PadY separately instead of only
  having the Padding option which did both.
* Improvements to Frame packing algorithm.
* Set the SDL draw mode to BLEND so we can use alpha colors properly,
  so now the dev console is semi-translucent.

e1cbff8c3f Add Palette Window and Palette Support to Edit Mode
* Add ui.Window to easily create reusable windows with titles.
* Add a palette window (panel) to the right edge of the Edit Mode.
  * Has Radio Buttons listing the colors available in the palette.
* Add palette support to Edit Mode so when you draw pixels, they take
  on the color and attributes of the currently selected Swatch in your
  palette.
* Revise the on-disk format to better serialize the Palette object to
  JSON.
* Break Play Mode: collision detection fails because the Grid key
  elements are now full Pixel objects (which retain their Palette and
  Swatch properties).
  * The Grid will need to be re-worked to separate X,Y coordinates from
    the Pixel metadata to just test "is something there, and what is
    it?"

41e1838549 Add JS + History to Shell, Add Main Scene
* The shell now supports an "eval" command, or "$" for short.
  * Runs it in an Otto JavaScript VM.
  * Some global variables are available, like `d` is the Doodle object
    itself, `log`, `RGBA()` and `Point()`
* The shell supports paging through input history using the arrow keys.
* Added an initial Main Scene

d560670b7b Better Collision Detection (Bouncy Jumps Up Hills)
* Add a debug view that draws the player bounding boxes.
* Improve the collision detection to add support for:
  * Doodads being "Grounded" so gravity need not apply.
  * Walking up hills, albeit a bit "bouncily"
  * Harder to clip out of bounds
