* Cancelling Interactive Preview now correctly restores the original Pose
* Interactive Preview now sets the correct active pose after it is run
* Interactive Preview now also updates the buttons window after it is run
* Clicking on the "New PoseLib" button now creates a new PoseLib action, even when one existed before
* Poses can be applied using the Pose browsing menu (i.e. when a menu item from that list is clicked, that pose is assigned)
