Pmail 20141107 rc

This is my first pass at the pmail exercise. A live version can be found here:

I tried out Yahoo's Pure (a watered down version of bootstrap)  to get the general layout, navigation, and buttons standardized. After using Pure, I would probably go back to using bootstrap or foundation as they provide a bit more out of the box without being complicated to learn/use.

The mail items are traversable with the up and down arrows using some quick Javascript/jQuery.
Can we drop the 'pure-' prefix?
