Get rid of sanitize dependency in docs #401
Description
If OSX didn't ship with Ruby 1.8.7, this wouldn't be a big deal, but it does and I would rather not make everybody jump through hoops to be able to contribute to documentation (and see what they're contributing).
Right now, even when using 1.8, sanitize has a nokogiri dependency that requires Ruby 1.9.2. I think there's probably something that could be done in those projects to fix this so feel free to take that path.
This dependency was introduced with #360.
