Address Navigation and Responsiveness Issues

There are some issues regarding browsing and navigating through the sermons in the Android Auto player that need addressing:

• Regardless of whether the player is currently playing or paused, browsing forward and backward always plays the newly loaded item
• Selecting the sermon from the list in the drawer does not navigate to the selected item, but stays on the current one
• Playing or pausing from the UI is often slow to update the interface, even after the audio responds to the request
• Pressing forward or backward causes the play/pause button to cycle from Play, Pause, Play on each navigation request. These changes to the UI seem unnecessary and distracting.
