Texture/Vertex/Index data cache (#132)

Browse Source 
* Initial implementation of the texture cache

* Cache vertex and index data aswell, some cleanup

* Improve handling of the cache by storing cached ranges on a list for each page

* Delete old data from the caches automatically, ensure that the cache is cleaned when the mapping/size changes, and some general cleanup
