Dasher accessibility integration

[Matthew Garrett <mjg59 srcf ucam org>]

I've spent yesterday and last night hacking some of the toolkit 
accessibilty integration that I'd mentioned earlier into Dasher. The 
code's not compilable except by hand at the moment, so I won't be 
releasing it just yet, but I've stuck a screenshot at 
http://www.codon.org.uk/~mjg59/dashercontrol.jpg . I've zoomed into the 
control node, selected gnome-panel and then dived down into the 
applications menu. Instead of that, I could have headed for an 
application and selected menu items from there. Currently I only look 
for menu items - toolbars would be a trivial addition. At the moment 
there's a lot of redundant stuff (a frame surrounding a menu results in 
an extra layer of boxes to dive through), but I'll look into stripping 
that out.
