cvsnt 2.0.60

Mostly this is just work on the installer.  There are one or two
minor changes.  It's now basically the same as the old one except it 
doesn't automatically generate a server key for sserver (which I hope to 
have working soon).

I've discovered that rename across directories isn't working properly, 
but the fix is non-trivial so it may be a little while before it's 
fixed.  Rename within a directory seems to be working OK.
