[Gnome-print] temp files

[Allin Cottrell <cottrell wfu edu>]

As of version 0.29, gnome-print doesn't clean up the temporary files
(postscript headers) it writes.  In fact it can't, because there is no
mechanism for remembering what the files are called.  The attached
little patch against gnome-print-ps2.c fixes that.

Sorry if this has been worked over already.  I have too many irons in
the fire to research gnome-print CVS.
