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))
REMOVE:: removed the Client and Server folders from the src folder
they were no longer necessary since everything now is in the GoGreen folder
EDIT:: edited .gitignore file
.gitignore file should now exclude the .idea and .gradle directories
FIX:: fixed the gradle build file.
had to set the main class, for testing purposes I set the GUI.logincontroller class as main class, but this will change
