Testing of loading models - read description.

Changed code for loading models, now using arrays within a function.
Still having issues with loading of textures - still running out of
memory.
More testing of loading models - read description.

Used Brian's resource management code to fix things slightly - all
models and textures now load but still a lot of memory being used,
waiting on fix from Brian for that.
Parallax Mapping maybe works? - Read description.

Added Parallax Mapping but not sure if it works properly, looks just
like Bump Mapping, hard to tell - may still need fixed/changed.
