When connected to a client, and then trying to connect to another, the connection manager component will be stopped(while the connect deferred is still running), so, the ConnectionManager.connection_manager reference will be deleted. If that's not the case, close the dialog.
Auto-connecting on start of the gtk ui is now fully working.
Auto-staring localhost if needed is now also working.
Authentication failures now get passed correctly to the client implementation which will allow the user to enter username and/or password to complete authentication.
It's now possible to shutdown the daemon from the connection manager even if not on localhost, it just needs all required information to be present on the liststore.
Auto-connecting to daemon now works. Fixes#1815.
Auto-starting a `localhost` daemon now also works, the reconnecting attempts were not being "triggered".
When not connected to a daemon, "Quit & Shutdown Daemon" is not present. So #1818 is also fixed.
Some more work regarding #1819 was done.
Client now disconnects before shutting down the GTK UI.
Moved some auth stuff to `deluge.common` because they're also used on the GTK UI.
Now, if a user starts deluge in classic mode and tries to change it to client/daemon mode, he see's a dialog stating that the current session will be stopped. If he answers no, nothing is done, the classic mode pref is set back as it was. If he answers yes, all components are stopped and client is disconnected. At this stage the user can open the connection manager to start the daemon and connect.
If the user starts in client/daemon mode and switches to classic mode he see's a dialog stating that deluge must be restarted.
The GTK UI connection manager now loads it's default config with the localclient username and password. If not present in the auth file, the auth file will be recreated.
All test were adapted, and some more were added to comply with the new multiuser support in deluge.
Regarding #1814, host entries in the Connection Manager UI are now migrated from the old format were automatic localhost logins were possible, which no longer is.
On the core, the code was not adapted to the new AuthManager. On The GtkUI, nothing was being shown to the user when errors occurred while changing ownership.
