This ports the following two function calls throughout Evolution:
• e_categories_get_list() to e_categories_dup_list()
• e_categories_get_icon_file_for() to e_categories_dup_icon_file_for()
It necessarily changes some internal e-util API:
• e_util_get_searchable_categories() to
e_util_dup_searchable_categories()
This bumps the EDS requirement to 3.13.1.
