The following textures now no longer render as blocks:
* Flowers
* Mushrooms
* Saplings
* Reeds
* Torches
Note that torches attached to wall are still rendered incorrectly
Re-factored the way the textures and blocks are being built. It should
be easier to understand and add new exceptions (sorta). Also fixed the
water and lava with other texture packs by putting a static water.png
and lava.png in with the code.
