Friendship card binder/flip card effect version 1 implementation. Added friendship card structure to friendships/index and added css and js for touch screen compatability. Deleted Sass and coffeescript files.
CSS twerks to friendship/index: shrunk cards, added border, changed background color, friend img size adjustments etc. Added container and spans to resemble a trading card binder more closely.
