Video fixes, input fixes, more cores supported

- OpenGL video now scales to the resolution on the main screen so retina displays look correct
- Swapped out control defaults for ones that work with OpenTK
- Migrated native core XCode projects from BizHawk 1.x, updated some of them to 64-bit for BizHawk 2.x.
-- Currently only blip_buf and QuickNES are added and tested
- Fixed QuickNES core, there's a windows specific floating point hack that we can safely omit porting because the problem it fixes doesn't happen on macOS / Unix.
