Configure additional assets to precompile

Fixes #4
ruby home setup
home.coffee removed
home / index route setup
updates to stylesheets, setting up correct dependancies
partial removed
modify scss require to remove output comment
Adding html-inspector javascript to page template
Configure Konacha for JavaScript testing
Spec helper
JavaScript spec helper
Configure localisation
Enforce localised URL convention for styleguide

Scopes the styleguide resource by locale but restricts it to the default
locale (en) only. This keeps routing consistent and ensures we have one
way to concern ourselves with how to determine the locale.
Introduce common base layout
Add localisation switcher to application layout
Remove empty home decorator and helper

We'll add them when if and when we have something to populate them with.
Add HTML5 Shiv dependency

The solution introduces Bower for front-end package management. Assets
will be checked into the vendor folder as is normal with Rails but we
gain the benefit of being able to describe our front-end dependencies
through the bower.json configuration file.
Enable HTML Inspector in development mode only
Use Bower to manage HTML Inspector dependency
Use Bower to manage normalize.css dependency
