SDK 1.3 release, and CVS shenanigans

I've released SDK v 1.3 (a quick poll suggested naming the SDK versions after the Axis version they complement). It's up on SF now.

I also had to do a lot of work in CVS following the SF CVS disaster a while ago, putting a load of orphan 1.3 code. I'm fairly confident its all there and with the correct verions, but if there are any problems post something up!
