Incorrect message name found when generate the messages.proto

[quesalltime]

While generate the messages.proto , the message name of the return value for smart contract's constant function is incorrect.

For example ,there is a smart contract contain a constant getName function which has no input parameter and return a string.
After convert the .sol file to the .proto files ,it will generate an unexpected GetNameReq message instead of generating GetNameResp message in the messages.proto.

# function in smart contract
function getName() public constant returns (string) {
      return name;
}

# After execute sol2proto , the expected message name in messages.proto
message GetNameResp { 
    string arg = 1;
}

# After execute sol2proto , the actual message name in messages.proto currently
message GetNameReq {
    string arg = 1;
}

After tracing the code , it seems to be a typo at line 59 in the grpc/method.go
I suppose the method.RequestName() should be replaced with method.ResponseName().

The corresponding PR is here #17
