Support for recipe inherits field

To identify image recipes and provide inheritance data for recipes, an
inherits field was added to the recipe model, and then populated using
refactored data from __inherit_cache. Finally the field was also added
to page templates, along with style changes proposed in attachment, and
an additional style change to display the inherits field as a list in
detailed view. The field skips globally inherited data as proposed.
