From 549708c6eaab2d0592c3e520e0debd82d64619b4 Mon Sep 17 00:00:00 2001

Subject: [PATCH] Add a separate "Save as" entry to the menu

The "Save" entry will now automatically save over the last used file.  If
no filename has been set, then that entry will also prompt the user for a
filename.

The filename is set when saving as well, so the next save will use the
same filename.
