08e65c32b5 Overhaul the Platformer Physics System
* Player character now experiences acceleration and friction when
  walking around the map!
* Actor position and movement had to be converted from int's
  (render.Point) to float64's to support fine-grained acceleration
  steps.
* Added "physics" package and physics.Vector to be a float64 counterpart
  for render.Point. Vector is used for uix.Actor.Position() for the sake
  of movement math. Vector is flattened back to a render.Point for
  collision purposes, since the levels and hitboxes are pixel-bound.
* Refactor the uix.Actor to no longer extend the doodads.Drawing (so it
  can have a Position that's a Vector instead of a Point). This broke
  some code that expected `.Doodad` to directly reference the
  Drawing.Doodad: now you had to refer to it as `a.Drawing.Doodad` which
  was ugly. Added convenience method .Doodad() for a shortcut.
* Moved functions like GetBoundingRect() from doodads package to
  collision, where it uses its own slimmer Actor interface for just the
  relevant methods it needs.

8965a7d86a Doodads: Crumbly Floor, Start Flag & State Blocks
Add new doodads:

* Start Flag: place this in a level to set the spawn point of the player
  character. If no flag is found, the player spawns at 0,0 in the top
  corner of the map. Only use one Start Flag per level, otherwise the
  player will randomly spawn at one of them.
* Crumbly Floor: a solid floor that begins to shake and then fall apart
  after a moment when a mobile character steps on it. The floor respawns
  after 5 seconds.
* State Blocks: blue and orange blocks that toggle between solid and
  pass-thru whenever a State Button is activated.
* State Button: a solid "ON/OFF" block that toggles State Blocks back
  and forth when touched. Only activates if touched on the side or bottom;
  acts as a solid floor when walked on from the top.

New features for doodad scripts:

* Actor scripts: call SetMobile(true) to mark an actor as a mobile mob
  (i.e. player character or enemy). Other doodads can check if the actor
  colliding with them IsMobile so they don't activate if placed too close
  to other (non-mobile) doodads in a level. The Blue and Red Azulians
  are the only mobile characters so far.
* Message.Broadcast allows sending a pub/sub message out to ALL doodads
  in the level, instead of only to linked doodads as Message.Publish does.
  This is used for the State Blocks to globally communicate on/off status
  without needing to link them all together manually.

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.

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)

1e80304061 Initial Doodad JavaScript System
* Add the JavaScript system for Doodads to run their scripts in levels,
  and wire initial OnCollide() handler support.
* CLI: Add a `doodad install-script` command to the doodad tool.
  * Usage: `doodad install-script <index.js> <filename.doodad>`
* Add dev-assets folder for storing source files for the official
  default doodads, sprites, levels, etc. and for now add a JavaScript
  for the first test doodad.

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.
