Trace - allow for similar fuzziness that vaasatog uses?

If a user searches for Crew or 702.122, search for 702.122a since that's the relevant thing.

Good idea. Couple of notes for my future self:

• I plan to change the glossary "get rule" API from fuzzy by default to exact by default. The trace API should use the same convention.
• The help text on the trace page has to be updated accordingly.
• There should probably be some visible warning whenever such a redirect occurs. I'll have to think of how that'll look.

Support for redirection from the base rule has been added in #34 and lunakv/academyruins-api#76 (see example trace). Redirection from a keyword is a little more complex, so I'm postponing that for later.
