GameMenu games can have a Main method instead of a menu
Add PackageLoader2.
- Doesn't have TypeLibrary inside
- Wraps HotloadManager
- Clear separation between loading the assembly and loading into typelibrary etc
- only used by Tools + GameMenu right now
- I broke fast hotload
Round the chunks in Graphics.Draw so when drawing Triangles they don't end up hanging over the chunk boundary
Add Draw.SolidTriangle
Enable fast hotload again
