Console catalogue sorting

Sort arrows are added automatically for all catalogue attributes when appropriate scopes exist on the model class. Scopes should be named sort_by_CATALOGUE_ATTRIBUTE_asc and sort_by_CATALOGUE_ATTRIBUTE_desc.

To add sorting by :use_count (when using attribute(:use_count) in a catalogue), add the following scopes to your model:

scope :sort_by_use_count_asc, -> { order(use_count: :asc) }
scope :sort_by_use_count_desc, -> { order(use_count: :desc) }
