new util: regtool.cc

[DJ Delorie <dj at delorie dot com>]

I just checked in a new program called "regtool" into
winsup/utils/regtool.cc.  It should show up in tonight's snapshot
(unless something else breaks it).  This is a small command-line
utility that lets shell scripts read and/or modify the registry (yes,
it can be dangerous, but you don't *have* to use it ;).  Usage text
appended.

If you can't wait, I put a copy at http://www.delorie.com/cygwin/regtool.cc
