* Phase 0 for user-selectable theme components - Drops `key` column from the `themes` table - Drops `theme_key` column from the `user_options` table - Adds `theme_ids` (array of ints default []) column to the `user_options` table and migrates data from `theme_key` to the new column. - Removes the `default_theme_key` site setting and adds `default_theme_id` instead. - Replaces `theme_key` cookie with a new one called `theme_ids` - no longer need Theme.settings_for_client
