Title: Dynamic height modal with pull page scrolling, rather than internal scrollbars

I previously submitted a pull request, but my code had bugs. Here is a version that looks to be good to go! The only thing I can't seem to get to work is the animation slide down/up - I can only get fade in / out. It may not be possible with a dynamic height modal though.
