[FEATURE] Replace repository forks

[EliteMasterEric]

The packages folder of the repository is used to contain submodules, representing forks of other repositories which required changes or fixes in order to function properly for the map. This is necessary for development, but is bad practice and the required changes should be added to the main project and the fork removed as soon as possible.

The following checklist breaks down each repository, why they were forked, and the status on merging the changes.
