Major Architecture changes on road to v0.3

1. Changed from float to using left and top. Nevertheless, all
transitions are done using CSS transitions and translateX.

2. Fixed issue where pages scrolled together. Now, pages scroll
independently of one another.

3. Page goes back to top automagically after another page has been
selected.

4. Swiping has been stabilized. Swiping vertically does not trigger the
page swiping so there are no more slight shaking of pages.

5. Code has less hacks! More modular!
