FW rendering fixes

[ExE-Boss]

This PR implements fixes for forward rendering.

List of fixes:

• Items now render in 1.7.10 (They still render as 3D in GUIs)
• Model face normals are now floating point numbers
• Calling MeshModel.newModel() now returns a MeshModel
• Calling CustomModel.newModel() now returns a CustomModel
