The new function is not complete, so the old one is still kept around.

For consistency the output arguments should always be the last
arguments of a function.

Programmed the two functions, loadMesh still copies all textures

[#79] Fixed some warnings, added breaks to switches, solved issue with texture glitches in voxelization

Finished some of the ToDos

The Mesh, posAccessor and vertexAttribues were only used inside the
scope of their loops and shouldn't have been sitting around in the
functions top-most scope.

For the same reasons as with the attributes, see a few commits prior for
more info.

The loadScene function has grown out of proportion and needs to be
refactored. As a first step, the parsing of vertex attributes has been
encapsulated into its own function.

This commit also adds the remaining PrimitiveTypes of vertex groups.

The name "print_what" is not self-explanatory...

deleted load_mesh function
added documentation
