Title: :moved class into seperate file, added ability to crop images

I created a wraith class and moved it into lib. Made images crop down so there isn't so much white space. PhantomJS seems to have a problem with window.innerHeight, so I picked 1500px as the default height, but if the window is bigger, it will just expand.

New dependency on Gem image_size.
