65a811db0d Auto-prune Empty Chunks in Level Files
* Discovered a bug where if you hit the Undo key to erase pixels and an
  entire chunk became empty by it, the chunk would have rendering errors
  and show as a solid black square instead of the level wallpaper
  showing through.
* Chunks that have no pixels in them are culled from the chunker
  immediately when you call a Delete() operation.
* The level file saver also calls a maintenance function to prune all
  empty chunks upon saving the file. So existing levels with broken
  chunks need only be re-saved to fix them.

6476a67faf Make Fire Deadly
* Touching "fire" pixels in a level will pop up the End Level alert box
  saying you've died by fire and can restart the level.
* Update level.WriteFile() to prune broken links between actors before
  save. So when a linked actor is deleted, the leftover link data is
  cleaned up.
* Slight optimization in Canvas.drawStrokes: if either end of the stroke
  is not within view of the screen, don't show the stroke.

35a89e5dbe WASM: Store User Files in localStorage
* In WASM build, user levels and doodads are written to localStorage
  using their userdir path as keys (".config/levels/test.level")
* LoadFile() and WriteFile() for both Levels and Doodads interact with
  the localStorage for WASM build instead of filesystem for desktop.
* userdir.ListLevels() and ListDoodads() for WASM scan the localStorage
  keys for file names.
* userdir.ResolvePath() now works for WASM (previously was dummied out),
  checks for the file in localStorage.

b17ca34de2 Bindata: Embedding Doodads and Levels (for WASM)
* Use `go-bindata` to embed built-in doodads and levels directly into
  the Doodle binary. `make bindata` produces the bindata source file.
* Add `FromJSON()` method to Levels and Doodads to load objects from
  JSON strings in memory (for bindata built-ins or WASM ajax requests)
* Update file loading functions to check the embedded bindata files.
  * pkg/config.go#EditFile:
    * Supports editing a level from bindata (TODO: remove this support)
    * If the "assets/levels/%(simple-name.level)" exists in bindata,
      edits that drawing.
    * No such support for editing built-in doodads.
    * WASM has no filesystem access to edit files except built-in
      levels (yet)
  * pkg/doodads#ListDoodads:
    * Prepends built-in doodads from bindata to the returned list.
    * WASM: no filesystem access so gets only the built-ins.
  * pkg/doodads#LoadFile:
    * Checks built-in bindata store first for doodad files.
    * WASM: tries an HTTP request if not found in bindata but can go no
      further if not found (no filesystem access)
  * pkg/filesystem#FindFile:
    * This function finds a level/doodad by checking all the places.
    * If the level or doodad exists in bindata built-in, always returns
      its system path like "assets/doodads/test.doodad"
    * WASM: always returns the built-in candidate path even if not found
      in bindata so that ajax GET can be attempted.
  * pkg/level#ListSystemLevels:
    * New function that lists the system level files, similar to the
      equivalent doodads function.
    * Prepends the bindata built-in level files.
    * WASM: only returns the built-ins (no filesystem support)
    * Desktop: also lists and returns the assets/levels/ directory.
  * pkg/level#LoadFile:
    * Like the doodads.LoadFile, tries from built-in bindata first, then
      ajax request (WASM) before accessing the filesystem (desktop)
* Menu Scene: TODO, list the built-in levels in the Load Level menu.
  This feature will soon go away when WASM gets its own storage for user
  levels (localStorage instead of filesystem)

f76ba6fbb7 WIP: MsgPack stubs, Level Filesystem Module
* Add some encoding/decoding functions for binary msgpack format for
  levels and doodads. Currently it writes msgpack files that can be
  decoded and printed by Python (mp2json.py) but it can't re-read from
  the binary format. For now, levels will continue to write in JSON
  format.
* Add filesystem abstraction functions to the balance/ package to search
  multiple paths to find Levels and Doodads, to make way for
  system-level doodads.
