[gtk+] a11y: Don't use signals

[Benjamin Otte <otte src gnome org>]

commit 66fae0330c5cdb68f50699ff2645ff0cf112911e
Author: Benjamin Otte <otte redhat com>
Date:   Fri Mar 7 21:45:18 2014 +0100

    a11y: Don't use signals
    
    Instead, call functions directly. Fixes the fact that the signals
    weren't disconnected even when the accessible was destroyed.
