[glade--]bug fix for empty combo list

["Howdy Pierce" <howdy cardinalpeak com>]

Hello--

I was attempting to add a Gtk::Combo widget in Glade with an empty list.
The elements in the list get added by my code after the myWindow_glade ctor
is called.  The problem with this is that glade-- generates incorrect code
in the _glade.cc file, resulting in the following runtime warning:

Gtk-CRITICAL **: file gtkcombo.c: line 954 (gtk_combo_set_popdown_strings):
assertion `strings != NULL' failed

Here is a fix for this -- it's a one-line change in src/writers/combo.cc to
ensure that the list has elements in it.
