Noah Petherbridge a43e45fad0 Level Collision and Scrolling Fixes

* Fix the level collision bug that allowed clipping thru a ceiling while
  climbing up a wall.
* Fix the scrolling behavior to keep the character on-screen no matter
  how fast the character is moving, especially downwards.
* Increase player speed and gravity.
* New cheat: "ghost mode" disables clipping for the player character.
* Mark an actor as "grounded" if they fall and are stopped by the lower
  level border, so they may jump again.

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.
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.
