doge api v2

v2 gives you the ability to add and manage users using the API. You can now create users (each one has their own address), get their balances individually, and move doge between them. We've also added a few useful functions that people have been asking for, such as a get_info action which returns a bunch of useful info in one call. You can also retrieve a list of transactions which match specific criteria.

v2 has the correct HTTP error codes, and a new JSON format for the data to make coding for it easier.
