User-provided path to JW FLV Media Player being overridden by _emfield_autodiscover_path()

When submitting a path for the JW FLV Media Player, emfield_flvmediaplayer_url() checks to see if flvmediaplayer.module is installed and, if not, calls _emfield_autodiscover_path() to return the path of the first discovered instance of 'player-viral.swf', 'player.swf' or 'mediaplayer.swf' overriding any path provided by the user.

User-provided path should have precedence and autodiscover should used only in the absence of a provided path.

(flvmediaplayer is not the only module that supports/uses jw flv player. In fact, it's not even the most current; LongTail Video's own jwplayermodule (http://drupal.org/project/jwplayermodule) is more current yet is ignored if _emfield_autodiscover_path() discovers any other player first.)
