Deinterlacing support for VideoSourcePlugin

I added deinterlacing support which makes 1080i or other interlaced sources watchable. It's possible to choose from all deinterlacing methods vlc provides. Also, in the VideoSourcePluginWrapper project you have awesomium.lib as a dependency, which seems like a mistake cause it isn't used at all and wouldn't make much sense anyway.
Would be nice if you could pull the changes.
