v5.1.1

This release we focused on the Conduct rework after user feedback. Also introduced some restriction admin-only setup pages and reports.

And several licensing problems were fixed.

- License Keys > Add raise a warning when a key is not active today, shows the dates the key is valid, and does not preselect users for an inactive key.

- The Grade Cards report can be exported to CSV with the same columns as the printed card.

- A quick note with a student and a category keeps both even when no score is tapped.

- Picking only a student or only a category shows a message.

- Teacher note signatures were removed from the Student Grid.

- The "Numeric averages" setting for conduct sections in report cards has a clearer description.

- Setup > Users and the other admin-only Setup pages open only for administrators.

- Library fines open only for librarians and administrators.

- Conduct History shows the text of quick notes saved with a mark.

- Saving a user profile whose license key is expired or not yet active shows a message instead of a crash.

- A failed profile save no longer removes the user's license key.

- Student group reports no longer break when a student has no first name.

Tested by Narcis Scirlatache in the development environment. This test included a brief look at the major parts of the app that were touched in development
