Full screen mode methods

[MichaelOstrovsky]

Hello. I've made an attempt to provide cross-browser solution to controlling full-screen mode.
Following is the solution so far ( combining all resources i could find and personal touches ).

Works on:
Win7 [ IE9, Firefox 18, Chrome 24, Safari 5.1, Opera 12.12 ]

Hope it helps anyone.
I'll be very thankfull for any corrections , feedback or test results ( and will update the script of course ).
