[cvsnt] Latest updates

[Tony Hoyle]

CVSNT 2.0.58b (stable)

* Spent time with the eclipse team trying to sort out issues.  This 
release is validated with the eclipse test suite so all major 
functionality should work without issue.
* Split the old 'fake unix' option into a group of compatibility 
options, which differ per-client (currently CVSNT and non-CVSNT).  For
most users leaving these disabled will be fine.  For eclipse clients 
enabling all 3 options in the 'non-cvsnt' category will give best 
compatibility.  The installer will sort this out for you if you were 
using the 'fake unix' option.
* Lots of mucking around with the internals to speed things up and sort 
out the remaining post-release bugs.
