[Vbox4php-develop] Session management changed

[Philipp <phi...@gm...>]

I have changed (with only 10 lines of code!) the whole session management.

I now use the PHP4 functionality for session management and no (own) local 
file is needed any more.

The old code is still there, I simply commented it out.

Okay, the code is not realy nice (should be moved to vboxIO sooner or later), 
but it works as I expect.

Please test and tell me your experience with it.
