After deleting (or renaming) a session, the point moves to
the next session (or the current session when renaming), however
the first session looks being selected since it is highlighted
using the `w3m-session-selected' face.  How about this instead?

* w3m-session.el (w3m-session-select-rename, w3m-session-select-delete):
Make the selected session highlighted after renaming or deletion.
(w3m-session-select): Allow specifying the session number.
(w3m-session-rename): Use the current title as the initial value.
