Start with namecoin connection module.

Create a still mostly empty module to encapsulate the
namecoin address query, and use it from the UI.
Basic implementation.

Implement very rough first query implementation, with
still hardcoded connection details.
Implement JSON RPC myself.

Write my own implementation of JSON RPC and HTTP queries, because
the jsonrpc module failed to let me configure what to do with
failed HTTP authentications.
