Changes to Blocked Enrolments for Conservatoriums

In v 8.0.30 and above blocked enrolments (only on Conservatorium Students screen) now have a couple of big BLOCKED ENROLMENT buttons (big red letters) across the screen. 
The record becomes inactive, the overview screen becomes blank and the status for enrolments is blocked

​If anyone tries to edit or add any activity to the record, they get a message saying the record is blocked and can't be edited. The record can only be unblocked by someone with Editing privileges (the mm or admin accounts).
