issue#46

This addresses issue #46 by storing a cache of changes, so that each db only subscribes to changes a single time.

Nice. I think the solution does the job.
Although, I'm not sure about how we should merge this in so I guess pinging @pgte seems appropriate.

I feel the tests should reflect the changes as well if possible.

As a suggestion, I feel we could push this a bit further because even if we're caching change subscriptions, we're still calling listen on each path, which downloads all documents from each db (so potentially from the same DB as well: https://github.com/yldio/pouch-redux-middleware/blob/master/src/index.js#L49). I think ideally we'd download docs only once for each DB, then apply the filters as needed.
