evazion 9759701071 search: add way to search array attributes by regex.
Add a `where_any_in_array_matches_regex` method and expose it to the API:

 * https://danbooru.donmai.us/artists?search[any_other_name_matches_regex]=^blah
 * https://danbooru.donmai.us/wiki_pages?search[any_other_name_matches_regex]=^blah
 * https://danbooru.donmai.us/saved_searches?search[any_label_matches_regex]=^blah

In SQL, this does `WHERE '^blah' ~<< ANY(other_names)`, where `~<<` is a
custom operator based on the `~` regex match operator, but with the
arguments reversed. This allows it to be used with the ANY(array) operator.
