[glom] Catch unknown command-line options.

[Murray Cumming <murrayc src gnome org>]

commit 1c586304524624b2eebbb6a6ed2883ffb1a16bfd
Author: Murray Cumming <murrayc murrayc com>

    Catch unknown command-line options.
    
    	* glom/main.cc: Put try/catch around the Gtk::Main instantiation
    	because I noticed that it throws an exception if you provide an
    	unknown option.
