[STABLE] Level/Tile/Mario Update

Additions:
- New tree tiles
- (Big) Mario can now crouch
- New level in "Original Mario" universe
- Cloud images; prep for the new level select menu

Fixes:
- Levels ACTUALLY change instead of loading the default that is preset.
- Because of this the level timer would not differ from other levels
(Which is why it was setting it to 100 every time, because it was
loading from the first level)

Notes: Fix the way setting up the world is done... organize the way the
player is handled, and get tubes in for pete's sake!
