[NEW] net/py-python-bitcoinrpc: Enhanced version of python-jsonrpc
for use with Bitcoin

AuthServiceProxy is an improved version of python-jsonrpc.

It includes the following generic improvements:

• HTTP connections persist for the life of the AuthServiceProxy object
• sends protocol 'version', per JSON-RPC 1.1
• sends proper, incrementing 'id'
• uses standard Python json lib
• can optionally log all RPC calls and results
• JSON-2.0 batch support

It also includes the following bitcoin-specific details:

• sends Basic HTTP authentication headers
• parses all JSON numbers that look like floats as Decimal, and serializes Decimal values to JSON-RPC connections.
