* Recolor some of the region doodads
* Add command: `doodad edit-level --remove-actor` to remove actors from
your level.

The Checkpoint Region acts as an invisible checkpoint flag, remembering
the player's location should they need to respawn there.
New cheat: `show all actors` during Play Mode will make every hidden
actor visible. Useful to see your technical doodads during gameplay!
Developer shell: `Execute(command string)` is available to the
JavaScript interpreter. It simulates another command being run on the
developer console.
