1523deeb9c Return False: Solid Collision Between Actors
* Implement the handler code for `return false` when actors are
  colliding with each other and wish to act like solid walls.
* The locked doors will `return false` when they're closed and the
  colliding actor does not have the matching key.
* Add arbitrary key/value storage to Actors. The colored keys will set
  an actor value "key:%TITLE%" on the one who touched the key before
  destroying itself. The colored doors check that key when touched to
  decide whether to open.
* The trapdoor now only opens if you're touching it from the top (your
  overlap box Y value is 0), but if you touch it from below and the door
  is closed, it acts like a solid object.

a2e1bd1ccb Improve OnCollide Doodad Script Handling
* Events.OnCollide now receives a CollideEvent object, which makes
  available the .Actor who collided and the .Overlap rect which is
  zero-relative to the target actor. Doodad scripts can use the .Overlap
  to see WHERE in their own box the other actor has intruded.
  * Update the LockedDoor and ElectricDoor doodads to detect when the
    player has entered their inner rect (since their doors are narrower
    than their doodad size)
  * Update the Button doodads to only press in when the player actually
    touches them (because their sizes are shorter than their doodad
    height)
  * Update the Trapdoor to only trigger its animation when the board
    along its top has been touched, not when the empty space below was
    touched from the bottom.
* Events.OnLeave now implemented and fires when an actor who was
  previously intersecting your doodad has left.
* The engine detects when an event JS callback returns false.
  Eventually, the OnCollide can return false to signify the collision is
  not accepted and the actor should be bumped away as if they hit solid
  geometry.

d28745f89e Mobile Enemy Doodad Test
* Add a Red Azulian as a test for mobile enemies.
  * Its A.I. has it walk back and forth, changing directions when it
    comes up against an obstacle for a few moments.
  * It plays walking animations and can trigger collision events with
    other Doodads, such as the Electric Door and Trapdoor.
* Move Gravity responsibility to the doodad scripts themselves.
  * Call `Self.SetGravity(true)` to opt the Doodad in to gravity.
  * The canvas.Loop() adds gravity to any doodad that has it enabled.

a73dec9f31 Doodad Animations Managed In-Engine
* Add animation support for Doodad actors (Play Mode) into the core
  engine, so that the Doodad script can register named animations and
  play them without managing all the details themselves.
  * Doodad API functions on Self: AddAnimation, PlayAnimation,
    StopAnimation, IsAnimating
* CLI: the `doodad convert` command will name each layer after the
  filename used as the input image.
* CLI: fix the `doodad convert` command creating duplicate Palette
  colors when converting a series of input images into a Doodad.

258b2eb285 Script Timers, Multiple Doodad Frames
* CLI: fix the `doodad convert` command to share the same Palette when
  converting each frame (layer) of a doodad so subsequent layers find
  the correct color swatches for serialization.
* Scripting: add timers and intervals to Doodad scripts to allow them to
  animate themselves or add delayed callbacks. The timers have the same
  API as a web browser: setTimeout(), setInterval(), clearTimeout(),
  clearInterval().
* Add support for uix.Actor to change its currently rendered layer in
  the level. For example a Button Doodad can set its image to Layer 1
  (pressed) when touched by the player, and Trapdoors can cycle through
  their layers to animate opening and closing.
  * Usage from a Doodad script: Self.ShowLayer(1)
* Default Doodads: added scripts for all Buttons, Doors, Keys and the
  Trapdoor to run their various animations when touched (in the case of
  Keys, destroy themselves when touched, because there is no player
  inventory yet)

241186209c Play Mode: Fix Level Collision w/ Scrolling
Fixes:
* Move the call to CollidesWithGrid() inside the Canvas instead of
  outside in the PlayScene.movePlayer() so it can apply to all Actors
  in motion.
* PlayScene.movePlayer() in turn just sets the player's Velocity so the
  Canvas.Loop() can move the actor itself.
* When keeping the player inside the level boundaries: previously it was
  assuming the player Position was relative to the window, and was
  checking the WorldIndexAt and getting wrong results.
* Canvas scrolling (loopFollowActor): check that the actor is getting
  close to the screen edge using the Viewport into the world, NOT the
  screen-relative coordinates of the Canvas bounding boxes.
