ClientApplication for the GUI, connects and most GroupServer aspects work. Added a constructor to the Client to make it easier. Also changed getIssuer() to getSubject() in several places where the username (and not the issuer) is needed.
Commit from laptop, thus in the middle of refactoring code. Group client frame is basically done, working on file client frame. In the middle of changing to the frames being in separate classes, stay posted for another commit later with this process complete.
Finished the file server client frame. All parts work except deleting a file...but that seems to be a problem on the server? Not sure. Also added deleting user from a group in the group server client frame.
Actually add the user created in the beginning to the group :) Fixed closing the window with active connections. Deleting works under Ubuntu 12.04.
Removed extra file.
