* FEATURE_USES_QUESTION_BANK is now a module_supports flag which declares
that an activity uses the question engine.
* question_module_uses_questions can be used to determine if a module
uses the question bank.
Sometimes it is necssary to display parts of a question outside of an
attempt. For example for staff review. When displaying the question, we
need to handle images in the question text. In the past there was a
mechanism for this that could only cope with the question text.
This commit introduces a new method that can handle displaying any
part of the question content.
This commit intentionally does not upgrade the parts of the system that
use the mecanism. That is so that this commit can be used to demonstrate
that backwards-compatibility works. The next commit will upgrade the
callers.
Even in the 'Error if grade not listed case', it was applying a small
tolerance. In the case of a fuzzy match, it was returning the inexact
grade from the import file, rather than the precise grade that Moodle
was expecting.
That causes problems when the editing form is displayed, because the
value from the database does not match any of the available options, so
the grade is changed to 0%.
NUMBER(X,Y) typically come back from the DB as strings. If you don't
convert them to float, then when you display them, it appears as
1.0000000, which is not normally what you want.
Also, increase the size of the field on the edit form, so if you
question does have default mark 0.1234567, you can see that!
I don't believe this will actually fix the reported problem, which I
cannot reproduce, but it should give us much better error messages, at
which point we can fix it.
New keep roles/enrolments and groups/groupings options, notification CSS fixed, standardised notification texts, added missing delete of module blocks, fixed file deleting and some other minor issues.
