[asterisk-gui] Nat translation

[Stephen Coles]

I can't see the nat option (but could just be my version or me) in the
advance options place

However with the gui looking so good as it is, its spoiled by that
horrible 'goto bar' position

Hope this is going to change - maybe just stick 'goto bar' at bottom of
options page instead of up the top or replace show advance options with
the goto bar

Im using:
	Asterisk 1.4.4
	Asterisk GUI-version Revision: 10695 $
