Since iTunes only has one playback queue, playing a new spot will stop playing that spot and start playing the new spot.
With the Pyglet player, it's possible to play multiple spots simultaneously, which is probably not what most people expect. Adding an explicit call to stop doesn't affect iTunes playback but explicitly implements behavior that was a side effect of iTunes mode.
Assuming you don't want to layer spots on top of each other :\
When Pyglet finishes playback, it will dequeue the source media. Calling `play` again will immediately pause, because there's no source media in the queue. This fix addresses that issue by checking the player queue state and requeueing the media if it expired out of the queue. This also addresses an issue where pressing play on two spots will allow you to play them simultaneously. Since the UI doesn't show that, I fixed the behavior to always stop playback. I also changed the behavior to make sure we start playback from the beginning, since the expected behavior of a "stop" button is to stop audio and reset the transport to the beginning of the track for future playback, not resume playback from the original timestamp.

Since I don't have iTunes or AppleScript on my machine, I got Pyglet playback working so I could test playback and the "play all" functionality in #3.
