Fix bouncing scroll-down arrow bug in webkit

Webkit transform currently requires a vendor prefix. Without it, the arrow bounces and rotate to the original un-rotated state. See https://www.dropbox.com/s/46sjiihtjya42s8/wk-rotate.mov

Optimize index.js and add style consistency

Declared all jQuery objects once where needed instead of diving into the DOM multiple times for the same object.

Added style consistency between variable declarations, if/else statements and functions.

Removed button backgrounds on static pages

The home and subscribe buttons had backgrounds on static pages, but not
post pages. The backgrounds are now removed from these buttons on
static pages.
Fixed bottom margin on static page post-title h1

Static pages were previously missing a margin on the bottom of the
post-title h1. By adding <header> with a post-header class around the
h1, we gain the exact same bottom margin as seen on post (non-static)
pages.
Changed button background fix to match post.hbs

As per JohnONolan’s suggestion, I have edited the nav to match the code
in post.hbs: https://github.com/TryGhost/Casper/blob/master/post.hbs#L9
