Move the matching in the launcher to its own struct and make it so the
matches are unique and we don't end up with 2 or 3 matches for the same
program. Change the priorities so that they are bundled together with
the fuzzy matching score and thus very good keyword matches will beat
out very poor name matches.
Keyword matches are always at a lower priority than name matches. It
would probably make sense to extend this into something smarter where
very good matches of keywords beat really poor matches of name.
