Calendar exclusions on Calendar tab

In v 8.0.44 and above, on the Calendar Entries tab (on administrator and teacher layouts), The yellow asterisk that shows if a calendar entry is clashing with a calendar exclusion can now be dismissed.

​Teachers (or administrator) can click the yellow asterisk to dismiss. 

​A message will appear asking if they are sure they want to dismiss the exclusion. They can click 'Cancel' or 'Yes'. If 'Yes' is clicked the yellow asterisk will not display again on that record.
