Implement OppoDeviceMessenger
* Add a bunch of custom style settings around object ordering
* Add basic docs, Wireshark traces
* Depend on Apache HTTPcomponents for web services (iffy on this)
* Miscellaneous classes, probably to be replaced down the road
* Fully threaded messenger class, NIO server + pool-based IO client
* Messenger deals in endpoint+JSON, hides all HTTP related concepts
* Single test case, dependent on the real device, that shows the basics
  are working (yay)
