displayed on cookbook version show. Since they are now no longer used
anywhere within the application this removes the breadcrumbs partial and
styles specific to the cookbook breadcrumbs.

to manage their profile on the user show view.
Adjust the user profile cookbooks language logic.

A user should see the username of the user profile they are viewing if that
profile is not theirs when that user profile has no cookbooks in the different
tabs.
