Consider replacing pyparsing with something better

Per discussion.

My complaints here are:

• utf8 handling is poor (huge performance hit so we only handle a reduced subset suitable for users of latin alphabet based writing systems)
• overkill for what we need (our grammar isn't that complex)
• stifles further grammar development because it's a pain to deal with

I think a standard argument parser (a la unix command-line argument parser) would work here, except matching any keywords in the query (excluding stuff inside double-quotes) and prefixing them with -- to make them into options. Thus:

,t prunella in plants by me -> ,t prunella --in plants --by me

That's essentially the approach suggested here in the accepted solution to this question:
