Wrapping up 2.2.

• Fixed a bug related to resolving links with parameters, so something like <MyFunction(int, int)> will go to the correct definition.

• Some finishing touches to the updated output style, which are pretty subtle.

That's it, plus some internal cleanup work.  Since everything seems pretty stable I'm deeming this a release candidate.  If nothing pops up in the next few weeks this will be 2.2.
