Add support for expandedWidth and expandedHeight - non-linears

The expandable companion is a format I’ve seen on Brightcove players, so maybe it is something custom for Brightcove??? On Brightcove it works like this:

--As soon as the preroll begins playing, the expandable ad is shown typically covering the playlist navigation portion of the player. Not all players are suited for expandables, there has to be some portion of the player to expand over.

--When the preroll finishes, the expandable ad disappears and the playlist navigation is visible again.

You can see an example here in the “asae2” video:

 http://www.adhostingsolutions.com/test/bc/brightcove3-ctn-demo.html. You can see the expandable covers the playlist and then collapses. On players with no playlist, the expandable option is not valid.
