Noah Petherbridge 97e179716c Add Technical Doodads + UI Fixes
New category for the Doodad Dropper: "Technical"

Technical doodads have a dashed outline and label for now, and they
turn invisible on level start, and are for hidden technical effects on
your level.

The doodads include:

* Goal Region: acts like an invisible Exit Flag (128x128), the level is
  won when the player character touches this region.
* Fire Region: acts like a death barrier (128x128), kills the player
  when a generic "You have died!" message.
* Power Source: on level start, acts like a switch and emits a
  power(true) signal to all linked doodads. Link it to your Electric
  Door for it to be open by default in your level!
* Stall Player (250ms): The player is paused for a moment the first time
  it touches this region. Useful to work around timing issues, e.g.
  help prevent the player from winning a race against another character.

There are some UI improvements to the Doodad Dropper window:

* If the first page of doodads is short, extra spacers are added so the
  alignment and size shows correctly.
* Added a 'background pattern' to the window: any unoccupied icon space
  has an inset rectangle slot.
* "Last pages" which are short still render weirdly without reserving
  the correct height in the TabFrame.

Doodad scripting engine updates:

* Self.Hide() and Self.Show() available.
* Subscribe to "broadcast:ready" to know when the level is ready, so you
  can safely Publish messages without deadlocks!
