feat(istream): implement TCP using ofxTCPServer

[nebgnahz]

tested with netcat and I can manually insert data point through tcp connections

Also, it looks like there's no explicit splitting of the input data into lines (e.g. based on newlines). That seems like it would cause problems if the client sends more or less than exactly one line of data at a time.

But maybe I'm misreading this?

[nebgnahz]

To be frank, I don't know what happens at those cases. This magic function setMessageDelimiter seems to be handling the line separation but I cannot judge much from the documentation (http://openframeworks.cc/documentation/ofxNetwork/ofxTCPClient/#show_setMessageDelimiter).

edit: I think if the message doesn't have line breaks, then the receive won't get back the data. If the message have one more line breaks, the worst case is dropping package (probably not a big deal..., but we can improve).

Whoops, sorry, I did miss the call to setMessageDelimiter()... That sounds like it probably does the right thing, but you're right, we may want to do some tests to make sure.
