[cvsnt] Latest updates

[Tony Hoyle]

CVSNT Development version 2.0.62.1859

I'm working towards a release ASAP so won't be doing much else other 
than fixing bugs from now on.  I'll try to release at least every couple 
of days when there's stuff to test.

* Lots of bug fixes
* mDNS/Zeroconf publication of repository information... no clients for 
this release so it's not so useful, but you get to set descriptions for 
the various repositories & the server.

Not done in this build:

* rcsinfo doesn't work yet - it got missed out.
* Documentation updates needed
