Bulk Delete Notification Scheme

When editing a notification scheme, its quick to grant Users / Groups / Project Roles access to any or all available notification events via the Add link under Operations.

However, reversing that process isn't a trivial process.

As admin, I want to delete all the default Notifications (Current Assignee, Reporter, All Watchers) for:

Issue Reopened (System)
Issue Deleted (System)
Issue Moved (System)
Work Logged On Issue (System)
Work Started On Issue (System)
Work Stopped On Issue (System)
Issue Worklog Updated (System)
Issue Worklog Deleted (System)
Generic Event (System)

To do that I'm required to Delete/Confirm 27 times, which is a tedious process and consumes productivity.

Ideally we could streamline deleting notification events by providing admins with the ability to bulk delete.
