Add room entry auto-triggers, player input, and more

* When you teleport to a room, the teleport auto-triggers fire.
* Rooms have auto-triggers. None by default. They are run every time you
  teleport to a room, and when the game starts. Gate behavior behind a
  variable.
* PlayerInputAction waits for player input (and potentially write it
  into a variable)
