Patch "Sink".1

Spoiler-Free Changes

• Updated the way doors (level & normal doors) are oriented when pushed into a "stuck" state. They'll now try orient themselves in such a way that the purple part touches a wall when the door is opened. In case they're pushed into a lone wall tile, they will not reorient at all.
• Added a gray wall tile which doors cannot be pushed into.
• The following levels have been altered to fix unintended solutions, none of which significant enough to reset completion status:
  • "Shove"
  • "Drill"
  • "Tower"
  • "Hold"
  • "Swap"
  • "Bridge"
