Jim note:
- Refactored code significantly
- Added a context menu option to exclude specific scenes from projectors
- Made it so multiview projectors update when scenes are
added/removed/renamed
- Increased text quality
- Removed the color sources and replaced them with simple solid
rectangles
- Increased the border size of "program" and "preview" scenes in the
lower scene list
