Changes to Enemble Roll MArking layout

In v8.1.06 and above there has been changes to  the formatting of the little '+' buttons that indicate a note has been entered for that week in Ensemble Roll-Marking layout.

 If the note says "CREDIT", the + button will be shaded red. This is to help conservatoriums (and some schools) that credit lessons back for ensembles or groups.

​​You can add 'CREDIT' as an option to the Notes dropdown list and that can be used whenever a lesson/session is to be credited back to the student. 

At the end of the term, the administrator can look through the rolls and make sure the number in the Allowable Absences column matches the number of red squares on a student's record.
​The 'Allowable Absences' column heading is now also an auto-sort button. This list will hopefully be helpful when working out the credits at the end of each term. (I will probably add a button to 'send these adjustments to accounts'. But not yet.)
