Further Freesound tweaks.

Make download of sound files multi-threaded. Each sound file download takes
place in its own thread, and has its own progress bar and cancel button,
which stack up from the bottom of the list of results.
Sound files download into a file with a '.part' suffix, which is then
renamed to the intended name on success.
Add a 'Similar' button, which searches Freesound for sounds similar to the
currently-selected sound in the results list.
