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
combined the contents of the two gradle build files into one, and put it into the root directory.
DELETE::removed pom.xml
deleted the pom.xml file, since it was used for maven and we use gradle in our project
