Priorities for rest of LTI sprint

[stianr]

Just summarising here what I think the priorities for the remaining time on the sprint should be:

The main priority is making sure that the LTI is working from City moodle - sorting out the current issue in #674, and testing (a) signin via moodle and (b) passing score to gradebook. Leaderboard is already tested and looking good.

After that, if time remains, two options:

Either: Start on a more challenging piece of work, either (a) the session-related issues in #655 - see my comment at the bottom, or (b) load testing the app now that it's on AWS - we never manged to get a full test with >100 students, see #557 and #553 for background. They're both imporant issues; probably not completable in the limited time left, but if it's possible to do a fairly self-contained part of the checking or fixing for one of these in the time, that would probably be a priority.

Or: If time is too limited, just a couple of bits of housekeeping - #662 so that lecturers can sign up for an account from the website rather than the app; #654 to space long module titles over multiple lines so that size blocks aren't pushed below the main block on the module overview page.

Updating this with a change of plan - thinking about the user experience, it's just become clear that some students will be taking both moodle-integrated modules, and standalone modules. At the moment we can't do that, so a priority would be to add to the functionality so that users can login both via moodle with no password, or direct to Quodl using a password. More details now in #678.
