1st Round of Doodad Sprites + Improve Doodad Tool * Improve the `doodad convert` command to convert a series of input images into multiple Frames of a Doodad: `doodad convert frame1.png frame2.png frameN.png output.doodad` * Add the initial round of dev-asset sprites for the default Doodads: * Button, Button-TypeB and Sticky Button * Red, Blue, Green and Yellow Locked Doors and Keys * Electric Door * Trapdoor Down * Add dev-assets/palette.json that defines our default doodad color palette. Eventually the JSON will be used by the `doodad` tool to give the layers meaningful names.

function main() {
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.

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.

Pub/Sub Messages Between Linked Actors (JavaScript) * Implement the pub/sub message passing system that lets the JavaScript VM of one actor (say, a Button) send messages to other linked actors in the level (say, an Electric Door) * Buttons now emit a "power(true)" message while pressed and "power(false)" when released. Sticky Buttons do not release and so do not send the power(false) message. * Electric Doors listen for the "power" event and open or close themselves based on the boolean value received. * If a Sticky Button receives power and is currently pressed down, it will pop back up (reset to "off" position) and notify its linked actors that they have lost power too. So if a Sticky Button held an Electric Door open, and another Button powers the Sticky Button, it would pop back up and also close the Electric Door.

Improve Collision Detection: More Active w/ Actors * Improve the collision detection algorithm so that Actor OnCollide scripts get called more often WHILE an actor is moving, to prevent a fast-moving actor from zipping right through the "solid" hitbox and not giving the subject actor time to protest the movement. * It's implemented by adding a `Settled` boolean to the OnCollide event object. When the game is testing out movement, Settled=false to give the actor a chance to say "I'm solid!" and have the moving party be stopped early. * After all this is done, for any pair of actors still with overlapping hitboxes, OnCollide is called one last time with Settled=true. This is when the actor should run its actions (like publishing messages to other actors, changing state as in a trapdoor, etc.) * The new collision detection algorithm works as follows: * Stage 1 is the same as before, all mobile actors are moved and tested against level geometry. They record their Original and New position during this phase. * Stage 2 is where we re-run that movement but ping actors being intersected each step of the way. We trace the steps between Original and New position, test OnCollide handler, and if it returns false we move the mobile actor to the Last Good Position along the trace. * Stage 3 we run the final OnCollide(Settled=true) to let actors run actions they wanted to for their collide handler, WITHOUT spamming those actions during Stage 2. * This should now allow for tweaking of gravity speed and player speed without breaking all actor collision checking.

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)
