WIP: Updating code to follow laupentin's code review.

Done:
- Moved custom map structures to their own objcommon header file
- Updated GfxLightGridRow struct
- Reverted shader_bin file path
- Renamed Project Creator to BSP Creator
- Removed model loading from BSP creator
- Cleaned up BSP Creator and updated the names of structs
WIP:
- Update BSP calculation code to be more readable and use unique/shared ptrs
