[Xpert]New extension for keeping track of client resources

[Mark Vojkovich]

   I've commited a new extension to CVS.  It's called "X-Resource"
and it lets you query how many clients are currently running and
how many of each type of resource they have.

   I've attached a simple client.


                                Mark.
