Cameron Ball c89d23ee6d MDL-41945 mod_assign: Properly check if submission is empty ... Previous empty submission checks required the submission to be saved to the database. This patch adds a new method to submission plugins that lets them report whether the submission is empty before it is saved.		2016-07-04 10:55:06 +08:00
