4d08bf1d85 Switch JavaScript engine to goja
* Switch from otto to goja for JavaScript engine.
* goja supports many ES6 syntax features like arrow functions,
  const/let, for-of with more coming soon.
* Same great features as otto, more modern environment for doodads!

810ba193d9 Doodads: Electric Trapdoor and Resettable Box
* New doodad: Electric Trapdoor. It is a horizontal version of the
  Electric Door. Opens while powered by a button or a switch and closes
  when it loses power.
* The Box doodad will reset to its original location if it receives a
  power signal from a linked Button or Switch. So for box pushing
  puzzles you can add a reset button in case the boxes get stuck.
* Refactored the Doodad build scripts into many Makefiles for easier
  iteration (don't need to compile ALL doodads to test one).

Updates to the JavaScript API for doodads:

* Self.MoveTo(Point) is now available to set the actor's position in
  world coordinates.

3892087932 Doodads: Use Key and Working Warp Doors
* The "Use Key" (Q or Spacebar) now activates the Warp Door instead of a
  collision event doing so.
* Warp Doors are now functional: the player opens a door, disappears,
  the door closes; player is teleported to the linked door which opens,
  appears the player and closes.
* If the player exits thru a Blue or Orange door which is disabled
  (dotted outline), the door still opens and drops the player off but
  returns to a Disabled state, acting as a one-way door.
* Clean up several debug log lines from Doodle and doodad scripts.

2c1185cc9f Doodads: Warp Doors, Bird, Larger State Blocks
* The blue and orange ON/OFF state blocks have all been increased in
  size to better match the player character (42x42 up from 33x33)
* Added a new mob: the Red Bird. It flies back and forth while
  maintaining its altitude, similar to the Red Azulian. Planned AI
  behavior is to divebomb the player when it gets close. Dive sprites
  are included but not yet hooked up in JavaScript.
* Warp Doors! (WIP). They have a golden "W" on them and come in three
  varieties: Brown, Blue and Orange. The blue and orange ones are
  sensitive to the State Block and will become dotted outlines when
  inactive (and can not be entered in this state). The door opens for
  the player character, makes him disappear, then closes again. The plan
  is it will then warp you to the location of a linked Warp Door
  elsewhere on the level, but for now it will just make the player
  re-appear after completing the Close Door animation.

38614ee280 Tighten Doodad JavaScript API, User Documentation
* Tightens up the surface area of API methods available to the
  JavaScript VMs for doodads. Variables and functions are carefully
  passed in one-by-one so the doodad script can only access intended
  functions and not snoop on undocumented APIs.
* Wrote tons of user documentation for Doodad Scripts: documented the
  full surface area of the exposed JavaScript API now that the surface
  area is known and limited.
* Early WIP code for the Campaign JSON

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.

7b3aec0fef Fix Two-State Blocks & Collision Detection
* Two-state Buttons now also subscribe to the state change message, so
  other on/off buttons in the same level update to match the state of
  the button that was hit.
* Add lock mutexes around the scripting engine to protect from
  concurrent event handlers.

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.
