Implement WieldMeshSceneNode which improves wield mesh rendering
- Don't create and cache an extruded mesh for every (non-node) item.
Instead use a single one per image resolution.
- For cubic nodes reuse a single wield mesh too
- Improve lighting of the wielded item
- Increase far value of wield mesh scene camera, fixes #1770
- Also includes some minor refactorings of Camera and GenericCAO.
