[TYPO3-english] Clear FE user session data on logoff

Hi, Jigal.

Yes, I also was looking into this, but I don't need so long life of data, so 
I rejected this way and made it a bit different: $name variable contains uid 
of current FE user appended - this makes sure, that only concrete user will 
see his related data.

Thank you! That sounds good, so I'll make an implementation :)
