[Gtk-sharp-list] setting Container.FocusChain to null.

[Peter Johanson]

Hey all,

Ran into this when I made an incorrect assumption about how to use
Gtk.Container.FocusChain. Currently, setting this to null causes a null
ref exception. At the least a check for null should be added. It also
seems to me that adding the behavior of "setting FocusChain = null is
the same as unsetting the focus chain" makes sense. Attached is a small patch
that implements that logic.

This make sense to do? Stupid idea?

thanks,

-pete
