Added support for using Squirrelmail without frames
(With many thanks to Jason Wickers (jwickers at scs.wsu.edu))
----
There are still a few minor things to iron out, but overall
it works fairly well at this point. Any plugin that calls
DisplayPageHeader() will now have to replace their </body></html>
with a simple call to noframes_bottom() to be compatible...
(Possibly rename that function to DisplayPageFooter in the future)
