Other notes:

- took the opportunity to remove MwLLSetBackground which I was told was deprecated
- Updated .gitignore to more accurately cover/remove example binaries
- Uses OpenGL as the backend.
- New LL function for swapping buffers, MwLLEndDraw
- [TODO] Uses weak linking for all libraries so that systems that don't support Wayland or even have it installed can launch without it.
