Allow selection of non-contacts in roster windows

Windows using RosterView (like for the invitiation/new chat dialogues)
have a search-box for filtering between contacts. This allows the user
to type a user ID into this search-box that isn't a contact's ID, which
can then be selected as the user.

This makes common operations (inviting a user/adding a new contact)
a little easier.
