CC-3391: Audio Preview cannot play tracks with commas in their filename

- The content distribution header filename attribute, wasn't properly quoted for inline content. This causes a bug for files with comma names.
- changed the play button in library back to the speaker icon
- removed some dead code preview_player.js
- removed the file name attribute, will need better approch to presenting the user with audio information.
