Make all mesh manipulators in mesh.cpp work with any vertex type
cloneMesh() has to use a switch in order to create a different mesh buffer type depending on vertex type. (Credit: the new cloneMesh was written by RealBadAngel.) To avoid repetitive code, all other methods use getVertexPitchFromType() to automatically adapt the indexing to the vertex type at runtime.
