[chirp_devel] Kenwood TS-2000 Support

I've been messing with Tom Hayward's initial work on the TS-2000 driver, and looks like it's working now.

Got read/write functionality working with my Kenwood TS-2000. Split mode is still broken, and I had to tool up the kenwood_live driver some in the process. I'll work on split later this weekend, but it's enough to send out to the list.

Looks like the past convention was to add the models directly into the kenwood_live.py file instead of separating them, and I haven't done that either.
