moving video support out of the QT previewer and checking for a plugin when working with QT VR panoramas.
making video size reactive like Quicktime preview so video stays within the page layout
Check for presence of Quicktime plugin and if it doesn't exist, try the HTML5 video tag for videos ... (Note that Quicktime for Windows is no longer supported by Apple and is being removed in organizations due to security concerns)
