Added JW player as new player-option. Uses Cloud-Hosted Player Code for license-sake. First try..
bugfixed and optimized: preview for JWplayer, made players recognizable for external scripts
Added posibilty to use a local player (in stead of cloud-hosted) for JwPlayer. This comes handy when your S3 videos are restricted by domains, since ALL IE browsers send a false refer-header (being that of the cloud-hosted players domain, not of the original webpage..)
Bugfix: JWplayer preview in S3 existing videos list
Bugfix for loading jQuery i iFrame file media_manager_insert_video.php. Now it loads jQuery through CDN in stead of the hardcoded way of loading WordPress' load-scripts.php?.. (can only load newer jQuery version when the colorbox plugin shipped with S3 is updated and vice-versa, due to deprecated -> removed jQuery.live() method)
