Add Player back widget to give feedback to users.

The player back widget allow users to : * load severals scripts * play all the scripts * stop/pause/play step by step one script * give feedbacks to the users All players are now QObject so that it's possible to retrieve the associated class name using the metaobject. This required to provide feedback associated with the newly introduced event type "comment". (See pqCommentEventPlayer)
