Make Disobedience login window work even when you're logged in.

Make Disobedience login window work even when you're logged in.

The previous code attempted to stop constant error messages when you
had a wrong password set by suppressing all disorder connection
activity when the login window was up.  This broke most activity in
the login window.  I don't really know why...

The new model has eclient stop making new connection attempts if it
gets an authentication error (it also disconnects when this happens).
So Disobedience now re-enables connection attempts when a
believed-good password is set.

Perhaps a future version will make this less ugly.
