Unfinished Wayland PR (#1)

moved from the github repo.

current progress:

<img width="389" alt="image.png" src="attachments/6a2cb365-7348-44b4-8fa7-9980df965a67">

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.
