Add delete-songs controls to admin request page

Operators can now select Version A and/or Version B in the Upload Songs
section and click 'Delete Selected Songs'. The handler removes the
chosen MP3 files, clears their DB paths, resets customer_approved to
'none', and sets the request status back to 'prompt_ready' so new
songs can be uploaded.

Bumps version to 0.5.1.
