Pref for setting wordclass in gnome-terminal

[Mike Bond <mike bond template com>]

Would be nice to have something in the prefs dialog for gnome-terminal
to be able to set the zvt wordclass, ie map to zvt_term_set_wordclass().
I've not worked at all yet with gnome/gtk gui coding, but I might give
it a try in a couple days if anyone else is interested in having me do
so as it probably is pretty simple.
