New Feature: Editing and Canceling of Pending Submissions

[Petie]

As I've said before, editing existing sheets is never going to happen. Site staff already have the ability to edit them but opening that feature up to the public would defeat the purpose of having the submission queue at all. You will, relatively soon, be able to submit revisions to existing sheets though. It will work in the same way that edits do now except that they'll be queued for approval by staff before going live.
