A few substantial changes:

- Tiles are initialized after being constructed which makes life simpler
  for custom tiles which no longer have to have their own constructor that
  passes Tile's stuff down to it.

- Tiles are no longer LRU cached (because we blow through that cache
  instantly on all but the smallest of scenes), and are now tracked by
  weak references so that we guarantee that only one instance of a tile is
  ever in memory.

- Added code to track and report memory usage of weak cached tiles as well
  as "stray" tiles which are created through other means than asking a
  TileSet for a tile (fringe tiles being the most prolific example).
