Subject: Add gui.group{arguments-gui.group.push, func}.

Convenience function that wraps func() in a push/pop pair, i.e.

	gui.group{grow=grow, spacing=spacing, size=size, pos=pos, function()
		do_stuff()
	end}

is equivalent to

	gui.group.push{grow=grow, spacing=spacing, size=size, pos=pos}
	do_stuff()
	gui.group.pop()
