[rfc] branch/merge/push/pull operations with remote location (sftp/ftp) that require password and GUI

[Alexander Belchenko]

I hacking Olive (Bazaar GUI) a bit and wondering how to implement
password dialog for operations with remote locations that require
authentications.

Current bzr code seems to be intended to use password request only with
console UI. I'd like to understand how to implement custom password
dialog. This is probably should be done like for progress bar?
