Add support for AdBlock

Overall design:

AdBlockManager (QObject)
- One per browser with a property saying if adblock is enabled.
- Owns all of the subscriptions

AdBlockSubscription (QObject)
- Constructed from an abp: url
- Owns all of the rules for this subscription
- Downloads rules when needed.

AdBlockRule
- Has a bool networkMatch(const QString &) function.
- Various properties such as if enabled, is a css rule etc.

AdBlockNetwork (applies network rules)
- QNetworkAccessManager uses this to see if a connection should be blocked.

AdBlockPage (applies css rules)
- WebPage uses this to hide elements.

AdBlockModel/AdBlockDialog
- Sits on top of AdBlockManager and presents a dialog to the user so
  they can add rules, subscriptions etc.

AdBlockScheme
- Handle the abp url scheme to subscribe to a new adblock subscriptions.

Misc:
- Added right click action to block
