SVN update

I've synced my local SVN with the Sourceforge copy so anyone can browse the work I've been doing on the dev branch. Check out the link below for a demo of how the backend works. It demonstrates the REGISTER functionality. You can see how to define a transaction using a python dictionary and then pass this off to the SIP agent to be processed.

Using this backend it should be possible to do state fuzzing of SIP as well as syntactic fuzzing of the headers. Conformance testing and stress testing should also be feasible.
