AuthServiceProxy has the following improvements over python-jsonrpc's
ServiceProxy class:
- HTTP connections persist for the life of the AuthServiceProxy object
(if server supports HTTP/1.1)
- sends protocol 'version', per JSON-RPC 1.1
- sends proper, incrementing 'id'
- sends Basic HTTP authentication headers
- parses all JSON numbers that look like floats as Decimal
- uses standard Python json lib
