This reverts commit 32efbeb9.

You can now add contacts from tags#show. Also, a CSS change to help us start refactoring: there's now a class to the body that you can set with content_for :body_class. This lets you scope CSS to a particular page. Started breaking out smaller CSS files.

Copyedit messages.

Fix append cucumber step to trigger keyup, so that it always copies the text from the placeholder input to the real input.
