Added the WedgeTexRemoveNull function. Currently texture coords are kept for ALL the triangles of a mesh. The texture id is stored with each face. 

if a given face should not have tex coord it has the default -1 value for texture ID. This function will add an new fake texture, add that to the list of textures and change all the -1 id to that value.
