Mentor groups
- Allows the import of mentor groups through the Admin
- During lab edit/create, teachers can select which mentor groups can enqueue in this lab
- Added option No group to choose which lab can allow students that are not in a mentor group
Also:
- Fixed bug where a default room on the enqueue form was already selected
- Fixed bug where a lab could not be created if no sign off intervals were used
Closes #85 (closed)
