jPlayer doesn't work when JS script aggregation is turned on

Hi,

The path being supplied for the jPlayer JS file starts with a '/' which means that drupal_add_js doesn't work when you have script aggregation turned on.

In audiofield_jplayer() I've removed drupal_add_js($player_path); and addded drupal_add_js($audio_players['jplayer']['path']); instead, which fixed the problem for me.
