open-cgf release 0.1

Well open-cgf doesn't get much attention, which is not that surprising given it's limited market appeal - you really have to own an SGSN or GGSN.

For those that are interested I have created a release tarball v0.1, which you can download from here.

Comments welcome. I need users who can run it against their hardware and report faults (and/or success!).
