Remove unused views and routes

To the best of my ability, I've verfied that everything removed
here isn't linked to or used as an end point.
Refactor pages into their own controller

Grouped style table view; implement tableView:titleForHeaderInSection

Generalize change locale link to work on any path
Refactor search for to Pages#home, create Retailers#index

Implements a Restful request 'retailers/ which returns
a list of retailers. Depreciates /retailers/nearaddy/,
however, doesn't remove because it is in use by iOS apps
Remove unused CSS, move Tropo script to lib

Removing unsed CSS will ease conversion to asset pipeline
Refactor Retailers controller to use RetailerPresenter

in the view easier
