daemon passwords stored in plain text

[brainchild]

Currently, in thin-client mode, the graphical interface stores passwords for remote daemons in plain text (on Linux in ~/.config/deluge/hostlist.conf).

Passwords should be handled through the desktop password manager (e.g. Gnome Keyring), for secure storage.

I understand that some may view this issue as a request rather than a bug. I am filing as a bug, because the current design creates a serious security liability for users, without their even being aware.
