MD3

Browse Source 
- finished support for multi-part player models
 - skin files are now read 
 - shaders are parsed, but not yet processed yet

DefaultIOSystem
 - file size is now cached over multiple calls to FileSize()

MaterialSystem
 - added AI_MATKEY_BLEND_FUNC property and the aiBlendMode enum to allow MD3 and Collada to pass transparency information correctly.
