Testnet genesis

Fixes #91. This branch merges in changes that @pennybreak manually included to create the genesis block and current version of the code that is running on the Peershares TestNet. To keep things consistent, I'd like to include these updates in the :master branch so we can build off of it without having to fork the network.

Note: This branch includes the intentionally disabled "OfficialNet" (due to the inclusion of a faulty genesis block).
