Reinvoked the Accessibility Wiki

Howdy List,

I currently rework the Plasma Accessiblity wiki.

https://userbase.kde.org/Accessibility/Plasma

I started with some inital stuff - how to start orca with:
- The shortcut
- autostart

next i will pin down how to enable (configure) teh magnifier (kwin  
ezoom plugin).

i will transform the Keyboard navigation section into an table with  
most useful shortcuts.

let me know what you think ( or even more needed some correction  
reading since i m not an native speaker nor an good english speaker lol)

there are currently about 4 wiki pages for accessiblity. i think best  
would be to unify them.

every bit matters! :).


cheers chrys
