Active admin Renamed from Admins => Admin

scoped_collection only returns ActiveRecord::Relation object (IE: User) , this needs to be scoped to our collection.  Adds new collection var to the index_with_email action to pass to the CSV export

There could be a better way to access the scoped_collection, however the only way i saw to turn off pagination for an action was to pass in the option :paginate => false.
