Changes and improvements

As we approach the final release, a few more bug fixes:

• improved memory usage and caching which reduces memory footprint of the server considerably. This has proved very successful for a college with 150,000 records in their database.
• The upgrade process in beta 2 was sometimes failing when upgrading from 0.7
• Each system user now has a email field which will tie into future features and notifications. This can be set by going to Preferences -> User
• When viewing a tutor record where list of classes being taught by the tutor were not displaying correctly
• Improvements to default views to improve performance with large numbers of records
  • Student window: lists currently enrolled students
  • Tutor window: lists tutors currently teaching classes
• Currency symbol ignored the locale settings and always used $ in emails
• Deleted sessions were still appearing in the calendar
• Enrolment confirmation emails sometimes not sent out
• Improved visibility split pane on Sessions on Windows platform – this split pane separates the timetable view from the list of sessions on the bottom. Prior to this fix, the split pane icon could not be seen easily.
• Further improvements to importing from external systems via xml
• Opening invoice window or creating a new invoice could hang the onCourse client
• Improved the appearance of printed certificates
• Profit and Loss reports for classes were not displaying balances correctly
