[Cris Dywan]

Rewrite Adblock more modularly, add Whitelist support

TODO:
- Expose filter metadata to user (name, last updated, time to next update)
- Check checksum hash of the subscription after downloading
- Remove subscriptions
- Open local files in editor
- Ability to disable adblock for site/for all sites via icon
- Save pre-parsed pre filtered ruleset into file as .preparsed
- Save matched/ cached uris from previous runs
