permissions -rw-r--r--
Attempt to fix issue #125. The password pop-up doesn't appear every time when going into the official server anymore, now it only does it when the password is blank. If a user enters an invalid password, the password is set blank to avoid the user going back to the official server just to be rejected. When entering an invalid password, the unknown error dialog doesn't show up anymore, but the connection lost to server one still does. This fixes the bug where the user would be spammed with error messages. The user can also now change his password in the settings page.
