EDIT:: Reimported project

reimported project to fix the errors in client application

FIX:: fixed the "location is not set" error in client application when loading fxml file

reimporting the project made it work, as it now has a submodule folder structure

EDIT:: edited settings.gradle file to include the modules in the new structure

EDIT: edited client build.gradle and server build.gradle files to pick the right common folder
(changed complie(:Common) to compile(:src:Common))
