Polymize

Alright, I'm going to throw this out here as the base for the app *frontend*. I've already shared some screenshots, now it's time to let you and others also play around, leave feedback, add issues for missing features, etc. etc.

Currently features the following:
* Show list of all music, with the BPM and artist clearly in sight
* Use the "re-index" button on the bottom right, enter a path, and the server will start reindexing
* Click on an item in the list
  * Play button allows for immediate playback
  * Adjust the BPM directly
