Title: ,U toggle message(s) as read/unread

This simple diff provides a binding to `U` to toggle the read/unread status of email(s).
The behavior is similar th the `*` binding, I actually renamed the `toggle_star` function to take care of both starring/destarring and marking email(s) as read/unread.
