Remove Tileo/ Classes

[MarkOates]

This is similar to #269, in this case the project was Tileo/.

The MeshWithNormals is particularly good, which is a tilemap where each tile also has a normal texture tile, and would be really great for cool lighting effects.

Special care should be taken to compare Tileo/ classes with the tile map classes in AllegroFlare/TileMaps (of which there are several forms).
