neon 0.29.x snapshot up for testing

[Joe Orton]

Hi.  I've put a snapshot of the current neon 0.29.x branch up for 
download here:

   http://www.webdav.org/neon/neon-r1717.tar.gz

It would be great if this could get some wider testing before tagging 
0.29.0.  Particularly the new NTLM auth support (thanks Kai!), which I 
haven't got test cases for.

Also, if anybody has got any outstanding patches which haven't made it 
in, now's the time to shout!  The current list of changes is included 
below.

Regards, Joe
