I made WorksController#update slightly prettier~
Split out WorksController#update_preview_mode helper function.
Deduplication ftw.
Use `saved` as the condition, as was done elsewhere.
Re-format a case statement to avoid the silly 18-space indent.
Cleaned up a few if statements in WorksController#new
Clean up WorksController#drafts.
Clean up WorksController#edit.
Well, WorksController#in_moderated_collection is slightly less terrifying, at least.
Cleaned up WorksController#in_moderated_collection considerably.
Whoops. set_instances_variables_work != set_instance_variables_create.
