phpagi

The File phpagi.php needs an error-handling for init the Class.
Cause i wan't to use the AGI-Class, and nothing happend.
After searching in my syslog i found, that in Line 1642 an error oure...
phpagi.php[1642]: mkdir(): Permission denied

I look into the function and see, that this mkdir not work, cause
permission in filesystem isn't set right.

I think here should me an error-handling insert, which check, if mkdir is
successfull or not, if not, should retunr false, to inform the
init-funktion,,, and to output an error to the user.
