Adds texture tracking.
I need to add a bunch more unit tests for the TextureManager
but this CL is getting large so if you don't mind I'll
do that in the next CL.
I still need to use the texture tracking at draw time but
that's going to require uniform tracking! UGH!
Also breaks out a bunch of the tracking classes into their own files.
TEST=none
BUG=none
