Corrected two errors, one which incorrectly assigns pitch to the

largest pitch among all the route layers (this may be harmless,
and is possibly overwritten later, but the code is clearly wrong,
so I fixed it).  The other error allows pre-routed nets from the
SPECIALNETS section to be ripped up during 2nd stage routing, and
since these nets can't be routed, they vanish from the layout
(except that they are dumped to the final DEF file, which almost
guarantees that there will be shorts).
