smix8 4185fce0ef Add wrong surface warnings to NavigationMesh.create_from_mesh() 
Adds warnings when at least one of the input mesh surfaces is of wrong primitive type or has an empty vertex / index array as those broken input meshes would fail as both navmesh as well as later when creating debug meshes.
