clapper: Implement harvest caching

Browse Source 
Using recently added local cache functionality, store harvests
that have expiration date. With this, next time the same URI is
selected for playback we can read it from cache, skipping loading
of any enhancer plugins and doing network requests.

This also works nicely with Clapper discoverer feature.
Making queued items be fetched and cached ahead of playback.
