Compile routine names as phrases

[ianb]

Right now we handle routine names very literally. You have to say pretty much the exact name. There's no aliases (which are mostly meant to fix common transcription errors), no stopwords, no repeated words, and no slots.

So I'd propose we compile routines into phrase matchers. We could really just use the compiler we have now, and then if someone wants to be fancy (using groups and alternates) they can. But more importantly, I'd like to compile all stopwords into (stopword |). That is, stopwords are optional, though allowed (and favored for scoring).

This also opens up manually inserting a slot, and using that as a substitution.
