SetName VNC Encoding

I decided to hold off on the zlib reset VNC encoding extension. I'm contemplating whether recompressing is an option (I want to avoid protocol extensions at all cost).

However, one extension that I know is necessary is and not terribly contraversarily is updating the name of the desktop. This extension is very simple, a new pseudo-encoding that is sent as a U32 that is the size of the new name, followed by the name.

That's it.
