[TYPO3-english] Show different page icon in BE when

[Loek Hilgersom]

Hi Jigal,

Thank you for the explanation and the code.

I renamed tx_iconClass to tx_myext_iconClass. The only other thing I had to 
change to make it work is that the iconClass should return 
'extensions-myext-mystate' instead of just 'mystate'.

Except clearing the sprites folder in typo3temp I also had to clear the opcode 
cache to see my changes, but it worked!

Thanks,
Loek
