Add additional options

Could you add the preload option?
https://flowplayer.org/docs/#video-attributes

Could you also add options for modifier classes?
https://flowplayer.org/docs/skinning.html#modifier-classes

Please could you make the preview look like the end result so add the Flowplayer to it?

Thanks,
