Improve UX on playing audio files

[jeffpaul]

Is your enhancement related to a problem? Please describe.
From @dkotter in #6:

Some weirdness between the audio blocks and the WebAmp player, where if you click the start button on the Audio block it seems to start the player instead (which may be fine) and if you remove an Audio block, it sometimes starts playing the next song in the player

Describe the solution you'd like
Review the work in #6, the current state of the develop branch, and what approach should (if any) be taken to resolve this issue.

@jeffpaul So far I've been unable to replicate the issue described. I've broken down what I tested and the results below:

Steps

1. Add Winamp Block to a page
2. Add multiple audio files from the media library
3. Attempt to play back the audio file from the regular audio block
4. Attempt to play back the audio file from the player preview
5. Remove an audio block and see if the audio starts playing
6. Remove songs via the player and confirm they don't actually modify the block children

Other notes/thoughts

• I would think that clicking the play button on the audio block should play the audio file in question, which is the behavior I'm seeing.
• Playing one audio file from the Block view doesn't autoplay to the next audio file (which I imagine is the intended result)

From here I'll need more detailed replication steps or I won't be able to really do much more with this. So far everything appears to be working as intended based on my tests.

@dkotter any recollection of more specific errors/steps from this?
