Include rdoc as a dependency

We've had some reports (#1342, #1809) of `rdoc` not being installed
in some environments, causing Gollum to error in unpleasant ways.

This isn't an issue that's unique to Gollum, and I don't think `rdoc`
should actually be a hard dependency of this project.  But since we can
side-step the issue by requiring `rdoc`, something that most users who
install Gollum via RubyGems would already have installed, I don't think
this is a horrible solution.
