Title: Allow Preference for Route Connectivity

Just out of a minor concern for privacy, allowing users to specify which
routes they'd like to hit to determine network connectivity. This is also
since google.com can be available in a capacitively-blocked network, thus
providing a false positive. One route Google Chrome uses to determine network
connectivity is http://clients3.google.com/generate_204 [docs][1].
