restyle items#index with box-shadow cards
seems OK with rails 4.1.8 and ruby 2.1.1
catch feature up
prefer sprockets
//= require over @import where possible
break up styles by view
include javascripts/items in manifest
more realistic images for seeds
don't need serve_static_assets in application.rb, but do want sass for css compression, and rails-sass
Merge branch 'feature/index-card-style' into develop
interim style change for index only
add livereload for easier style-fixing
