Remove everything about compiled files

Just a refactor that doesn't affect any script or add anything new.
Plutonium T6 now supports loading source scripts so compiling them isn't needed anymore
https://plutonium.pw/docs/changelog/#r3408

[Refactor]
Removed all compiled scripts
Moved all source scripts to the main folder instead of a source folder
Renamed all source scripts to remove the source tag at the end

Removed notions of compiled and source scripts in the repository's README
