LDEV-4816 use jquery toggle instead of bootstrap collapseBy some reason bootstrap collapse doesn't work properly. Involvedlinks got assigned double amount of click handlers which makesthem appear and then instantaneously disappear again.
LDEV-4765 Further UI improvements* True/False type of questions now use bootstrap-toggle widget* Update jqeuryvalidate plugin. And make it show bootstrap-like warnings* Disable autocomplete for all form inputs* A few other minor fixes
LDEV-4746 Set default mark when QB'ing MCQ questionsA default mark of 1 was set during question creation in authoring. Sincenow we import instead of create, it is better to also do it duringmigration.
LDEV-4813 Use tables only if a condition is providedIf tables are used and no condition which uses them is provided, a fullouter join is run. It takes ages to complete on a large instance.
