Create the dashboard & welcome views.

The dashboard is what an authenticated user sees. It displays the activity feed
for the cookbooks they follow and easy to find links for the cookbooks they own
and contribute to.

The welcome page is what a non-authenticated user sees. It introduces them to
what Supermarket is and highlights what they can do on Supermarket.

The content is not all fleshed out yet, but it will soon include things like
featured cookbooks, cookbook activity feeds and the cookbooks that a user owns
and contributes to.
Merge pull request #270 from opscode/dashboard

Create the dashboard and welcome views.
Remove lvh.me recommendation from the README.

The README referenced an OmniAuth provider that we no longer use, and I have not
run into any issues using localhost when developing locally with GitHub and
oc-id as OmniAuth providers. A more concise README is never a bad thing.
Merge pull request #275 from opscode/lvhme_readme_update

Remove lvh.me recommendation from the README.
Remove the cookbook categories nav.

The category nav is of questionable value, so for the time being the nav is
being removed.
Use the cookbook category on the cookbook partial.
Start styling the new search bar.
Make global searchbar & update globalheader style.

The big ole search bar is now on every page. It should be hidden by default on
most pages, and a little button can hide and show it.

This also updates the header to be white and go with Dan's mock-up. The chef
logo probably needs to be changed to not be white on white. :)
Add search bar toggle to the nav.

By default, the search bar is hidden. If the q param is present, the search bar is
displayed. The search bar is removed from all other locations but the
application layout.
Change the body and page background color.
Remove the temp stats from the cookbooks directory.
