- minor typo fixes, clarifications, etc.
- keep sts.html url consistent, because many people link to
http://sitaramc.github.com/gitolite/sts.html
- create a common migration doc, so the old 'migr.html' does not 404
when g3 docs become "main"
- progit doc done
- add gitosis convert script (FWIW)
- a minor comment fix to Sugar.pm
