Author: Alexander Butenko <a.butenka at gmail.com>

Simpler element hiding and some adblock optimizations
1. Less hungry and simpler blocked element hider
2. We are now also adding a context menuitem for uris in
preparation for creating rules from the web inspector
3. Removed old hack for blocked element hider
4. Element hider javascript fixes
5. Unit test for small sized rules
6. Removed unneeded WebKitWebView casts
