Rise and Fall, Developers Update

Changelog

1. Makes mod compatible with RnF and recent patch.
2. Major overhaul on how lenses were added to the mod. Makes it really easy for developers to add new lenses without editing my mod files. So lenses can be their own mods.
3. Builder lens enhancements. Resource hex is highlighted if it has an incorrect improvement on it (example uranium on a farm). Removed red hex (ie "nothing to do") from improvements and district and wonder lens. Fixes issue with having a sea of red tiles in late game.
