Question banks were displaying in places they shouldn't, because
FEATURE_CAN_DISPLAY wasn't fully implemented. This broadens its
usage in the following areas:
- Availability info - Not relevant to qbank. However you could feasibly
have some module which isn't shown to students, but the teacher can
use
it to track completion, so dont display the link.
- Activities block - links to each activity's index page. We already
have
the Question banks page in the secondary nav. No need to have it here
too.
- Overview report - It doesn't make sense to display question banks
here,
as they're not an activity students can participate in, they wont have
dates etc.
- Externallib - Return with candisplay = false. The app needs to handle
this correctly.
- Visibility options, moodleform_mod, modvisible and visibility
selector.
Not relevant for qbank since it doesn't include the standard
coursemodule
options, but if an activity with without CAN_DISPLAY did display a
visibility setting, "Hidden" should be the only option.
- Activity names filter - we dont want automatic links to question
banks.
