MAJOR UPDATE
* changed from previous layout to MVC layout, which is fantastic! However, this came with a few changes to classes that handled GUI elements before
* Added GameModel instance class to keep track of game elements
* Added EventHandler instance class to keep track of all input events (from device and from connected devices)
* Made EventHandler and BluetoothManager watch event queues via interrupts, which is most efficient and working great
* Insane multi-threading. Uber-fast stuff
