We've got a wiki!

This has been in gestation for far too long, but we finally have a documentation wiki. We've also moved our user forum over there, since the old one (provided by Squarespace) sucked and was rarely used. We will be redirecting documentation links there over time. The wiki versions of documentation will be the most up to date and authoritative from now on. Not all products have documentation in the wiki yet, but we hope to fix that over the next couple of weeks.
