HEAD
- Use LON-CAPA standard table for quick grades table
- Keep multicolor background settings, but switch from HTML attribute "bgcolor=..." to style="background-color=..." needed to keep this functional
- Corrected table row closure (was "<tr>" instead of "</tr>")
- Added missing &mt() call to introduction text for detailed scores table
- Added info style to info text about time consumption
