dialog titles should match command names
Submitted by Adam Dingle
According to the GNOME interface guidelines, a dialog's title should be the name of the command that opened it:
In Gnumeric this is often not the case - e.g. File->Open opens a dialog "Open Spreadsheet File", Save->As opens a dialog "Save the current workbook as" and so on. We should fix these dialog titles to match their associated commands.
