Add support and upgrade to lucille 0.0.3

Of note, this PR introduces a regression.
We no longer use per-field analyzers in QueryAnalyzer.
I've created a followup issue for fixing this: #257

Sam and I talked a bit about this per-field analyzer regression business.

In short, it's not possible with the current/new traverseQ function.
Because you can't actually do anything with a Field query in the traverseQ function, you can only touch the TermQuery "leaf" nodes. And what you actually need to do is use the Field query's field name to find the right analyzer, and then start using that analyzer.

If we want to do something "per-field" then i guess we need a more powerful function than traverseQ

it's kind of a can of worms.
If you give me a Query => Query function to apply to some Query
What do I do when I hit a Query.And? do I apply it to the subqueries, or do I apply it to the Query.And itself? or like, both maybe?

I think maybe we need something like:

query.traverseByField {
  case "author" => lowercase
  case "body" => lowercaseAndSplitWhitespace
}

And of course a mapByField would be nice too.

Oh well, more fun for the future.
