Added sidebar & restructured for flexible design

I added a sidebar in that shows events per day. Also added a custom
sidebar using NiceScroll.js

I restructured all of the CSS to be a more fluid and flexible design
that dynamically resizes almost everything in the design based on
browser window size.

Fixes #6 and #7
Added left and right arrows

Added the icons for the right and left arrows.
