Update payment protocol to match Dogecoin (#1433)

Browse source 
* Revised payment request handling to use genesis block hash instead of network name, enabling
support for more networks that just Bitcoin main and test net.
* Disable payment protocol certificate unit tests; we don't modify this code, and regenerating the test data is likely to be significantly time consuming. Will re-enable once discussion on spec is concluded.
