Doodads: Small Key Door + Bigger Crumbly Floor

* The crumbly floor doodad was made 50% larger.
* New doodad: Small Key and Small Key Door. These work like the colored
  doors and locks except each Small Key is consumed when it unlocks a
  door. The door's appearance is of iron bars.
* The inventory HUD displays a small quantity label in the lower-right
  corner of items that have a quantity, such as the Small Key. This is
  done as a Canvas.CornerLabel string attribute on uix.Canvas.
* The "give all keys" cheat adds 99 Small Keys to your inventory.
