145th update: Theme Sorter + Single Files 4/7

update v16.8

A few updates to make everything tidier, since the asset pack is getting massive 

- Started producing all the single files, this is a super long process since I've decided to name them all also based on the sprite and not only based on the theme
- Added all the "Worksite" theme single files
- Added all the "Villas" theme single files
- Added all the "Generic_Building" theme single files

See you and happy game-making! :)
