Noah Petherbridge 0e3a30e633 Fix Actor Collision Checks Again

* Recent collision update caused a regression where the player would get
  "stuck" while standing on top of a solid doodad, unable to walk left
  or right.
* When deciding if the actor is on top of a doodad, use the doodad's
  Hitbox (if available) instead of the bounding box. This fixes the
  upside-down trapdoor acting solid when landed on from the top, since
  its Hitbox Y coordinate is not the same as the top of its sprite.
* Cheats: when using the noclip cheat in Play Mode, you can hold down
  the Shift key while moving to only move one pixel at a time.

Cheats

unleash the beast - disable frame rate throttling.
don't edit and drive - enable editing while playing a level.
scroll scroll scroll your boat - enable scrolling the level with arrow keys while playing a level.
import antigravity - during Play Mode, disables gravity for the player character and allows free movement in all directions with the arrow keys. Enter the cheat again to restore gravity to normal.
- Note: under antigravity, hold down the Shift key to lower the player speed to only one pixel per tick.
ghost mode - during Play Mode, toggles noclip for the player character.

Bool Props

Some boolean switches can be toggled in the command shell.

Usage: boolProp <name> <value>

The value is truthy if its first character is the letter T or the number 1. All other values are false. Examples: True, true, T, t, 1.

Debug or D: toggle debug mode within the app.
DebugOverlay or DO: toggle the debug text overlay.
DebugCollision or DC: toggle collision hitbox lines.

Interesting Tricks

Editable Map While Playing

In Play Mode run the command:

Command	Effect
`$ d.Scene.Drawing().Editable = true`	Can click and drag new pixels onto the level while playing it.
`$ d.Scene.Drawing().Scrollable = true`	Arrow keys scroll the map, like in editor mode.
`$ d.Scene.Drawing().NoLimitScroll = true`	Allow map to scroll beyond bounded limits.

The equivalent Canvas in the Edit Mode is at d.Scene.UI.Canvas

Edit Out-of-Bounds in Editor Mode

In Edit Mode run the command:

$ d.Scene.UI.Canvas.NoLimitScroll = true

and you can scroll the map freely outside of the normal scroll boundaries. For example, to see/edit pixels outside the top-left edges of bounded levels.
