Corrected javadoc and the implementation of the save method now correctly handles updates
implemented change password method in the service layer
updated to spring 3.2.3 because there was a bug in version 3.2.1 that made validation groups not work correctly
started a change password feature. it already works but the page is still ugly and there is no password changed successful message yet.
Renamed the RegistrationFormBean to UserFormBean so it can be used with the change password as well. Therefore I introduced validation groups so the email is not validated for the password change
