Bug Description

And by large I mean even normal 20 students x 30 lessons

Changed in schooltool.lyceum.journal:
importance: Undecided → Critical
assignee: nobody → Justas Sadzevičius (justas-pov)
status: New → In Progress
milestone: none → 1.9.2

Profiled it a bit. Slowness seems to be caused by:
- overzealous security checks
- complicated/large template rendering
- in some part by data storage/retrieval

Cleaning this up some is a high priority.

Fixed the overzealous security checks. Bug considered fixed, the template rendering slowness should be fixed separately.

I will look if this speedup can be applied to older schooltool.
