Neo City + Revamped EllinPQ + New Release

Fixed Neo City area, now playable.
Overhauled the EllinPQ mechanics, such as the "CLEAR" effect when passing maps, and some bug fixes along the way.
Refactored a lot of out-of-place classes and properly renamed a few others through the project.
Updated readme and licenses through the source, preparing the stage for the new release.
