Adds a template for the 2013 review in the standalone folder
removes 'standalone' folder for the 2013 review page.

i think flask wants us to use Blueprints for this, which is too heavy.
so instead just mixing it all in with the rest of the app. not ideal but
good enough since this is so far a one-off.
the intro screen works, and the number position works.
mostly works.
adds icons, moves numbers up a bit.
adds 2013.css
