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.
Implemented Guild PQ. Fixed a problem introduced earlier where negative
EXP would be deemed as "integer overflow", provoking many game breaking
issues as result.
