1. The length of time which unreachable scripts are blocked is now configurable in settings.
2. A new option to redirect non-framed URLs for URLs that are also unreachable.
e.g., https://www.ubuyit.com/redir?u=http%3A%2F%2Fwww.yahoo.com
When the former URL is not reachable, it takes you to the second URL.

Ignore requests that were aborted, due to user canceling the navigation.
