DAIRemote App Settings Page (#137)

* Implemented DAIRemote App settings page, allowing user configuration of auto connect, heartbeat timeout, heartbeat interval, and maximum missed heartbeats.
* Implemented modifying default audio device for display profile tiles on DAIRemote desktop application window for each display profile tile.
* Updated README.md instructions.
