Mentor Graphics KeyGen 13.10.40.0

As Mentor now has gone CRO, making a working license has become an "almost" impossible task. Also all programs are now checksum or CRC32 checked, so any patch will show up and programs will abort. This KeyGen was been rewritten from scratch, so it does not have any more an internal feature list. It will, instead, read and analyse all mgc.pkginfo for the required features.
