#2 Move Status widgets off of main menubar

[Brian Murphy]

This patch moves the status option menu and mailbox
status pixmap from the main menubar to a row of their
own. The menubar is then extended to fill its
horizontal bar. The pixmap is put into a button so it
can be clicked. A menu option has been added to allow
the hiding of the status bar. A matching show_status
boolean configuration option is also added.

This patch requires my previous "Show/Hide Chat Button"
patch (Request ID 494504) for the Show/Hide infrastructure.
