swig_bot remote path connection / preliminary implementation.

With this patch, the client will package up all the required
inputs into a compressed zip file, establish a connection to the
server, send the input to the server, and wait for the server to
send a response (in this case the response is just echoed back to
the client).

This gets the network communication in place, and in a subsequent
patch I will follow up with the code that actually runs swig on
the server and sends back the output instead of echoing back the
input.
