A suggestion with keyboard accessibility enable setting with Natty

[Hammer Attila]

Hy,

I attached longer time ago a Casper package related patch for 
30accessibility script to prewent a disturb problem for a default 
enabled gconf setting for keyboard accessibility with some blindness 
related profiles.
With screen reader usage disturb the default enabled keyboard 
accessibility setting for example if the user muting screen reader 
ciclical with shift key.
Please review my patch for following bugreport, and if my patch are 
good, please commit for Casper package in Natty:
https://bugs.launchpad.net/bugs/711131

For example, if I ciclical muting Orca with shift key with an apt-get 
upgrade operation output, and the keyboard accessibility setting is 
enabled with access=v2 and v3 profiles, always a popup notification 
question is presenting I want turning on the sticky keyboard 
accessibility mode (hopefuly I remember right the popup question).

Thank you the reviewing,

Attila
