 In [changeset:"36580"]:
 {{{
 #!CommitTicketReference repository="" revision="36580"
 Themes: After [36546] restore theme search functionality.

 * Correct several incorrect uses of `_.union`. Since Underscore 1.7.0
 `_.union` supports only arrays and not variadic args.
 * Use a namespaced event `themes:update`. Backbone 1.2 added a built in
 `update` event that triggers after any amount of models are added or
 removed from a collection.

 Props adamsilverstein.
 See #34350.
