JSON-RPC 2.0 5.1 Error object

Adding custom exceptions

By default dispatcher catches all exceptions in registered methods: https://github.com/mbr/tinyrpc/blob/1.1.4/tinyrpc/dispatch/__init__.py#L266

        except Exception as e:
            # an error occurred within the method, return it
            return request.error_respond(e)

and exception e is wrapped as response using RPCRequest.error_respond():

• RPCRequest.error_respond()
• JSONRPCRequest.error_respond()
• _get_code_message_and_data()

TODO: How to provide more detailed exception do client - i.e. exception type and backtrace ? Possible solutions:

1. Create own RPCDispatcher with own dispatch() method, where exception will carry also .data
2. Create own JSONRPCProtocol with changed JSONRPCRequest().error_respond(), where full exception is unwinded and serialized in JSON data field.
