Title: Make images content based instead of metadata based. 

I added the ability to pull in an image from a slide to be the full screen image. This way, if you wanted to show the image one way in printing, and another way in preso mode, you could.

Additionally, i moved the target of the background image to the state background instead of the body. This allows you to apply css to the image if you want to independent from the entire document.
