Implement support for Python http.client

The full class might be to big, so maybe it only makes sense to implement a subset of it including the most important features.

I think this one can be done in pure Python, using the underlying sockets implementation. See micropython-lib: https://github.com/micropython/micropython-lib/tree/master/http.client

Thanks for the link. Well, that would be perfect!!
I'll give it a try on the CC3200 ASAP and I'll come back with the results.
