Title: Changes to make modal accomodate any content height and have the whole page scroll, rather than internal modal scrollbars

Makes using for modals for apps a lot easier when they can accomodate any content height. I noticed there was an issue with people asking for it (https://github.com/twitter/bootstrap/issues/407) and I wanted it myself. I took notes from how Trello handles this.
