it
MDL-34695 wiki: ensure the correct individual subwiki is used/created for a user

MDL-36336: Prevent duplicate grade items on restore

During restore, lti_add_instance() was being called
and this could generate a grade item.  This would
produce a duplicate item because the restore
process would automatically generate the grade item.
MDL-36305 theme: Forum reply button is not removed using MyMobile
MDL-36551 - mod_data: Onsite presets now retain the advanced search template.

Presets that were saved to the site would lose the advanced search template when being used.
The previous check was put in place to see if the advanced search template existed or not (presets pre 1.9),
This checked external files properly but not onsite files.

Now checks are being done on both internal and external preset files.

MDL-36763 Remove onclick event when creating activity left indent link

The left indent onclick is now handled by a Y.delegate so there is no need
for a seperate event handler.
MDL-35819 Improve performance of help tooltip

Rather than using an event handler for each help link, we add the
'helpicon' class to them and delegate the display function.

In order for this to work, we modify the way that Y.io fetches the help to
use the intended target of the anchor rather than a value provided in the
add call. We also no longer modify this URL and instead add the ajaxurl
parameter to it using the Y.io data parameter.

This change is backwards compatible with people calling it without using
the help icon renderer.
MDL-36760 formslib: fix frozen elements with [] in name.

This was a regression caused by MDL-30845 or, to be precise, the related
issue MDL-32785.

Form elements with names like multipier[0] require special handling,
such as is present in HTML_QuickForm_element::_prepareValue. I have
added equivalent handling to MoodleQuickForm::exportValues. I am afraid
that I could not think of a way to do this reliably without duplicating
code.
MDL-36806 question files: fix unnecessary require_login call.

quiz_question_pluginfile later does the correct check. Doing this
other check first means you get an error about changing $PAGE->context.

MDL-36795 - lib / administration: maxsections now limits the default setting for numsections.

In the default course settings, setting the maximum number topics / weeks  to 0 would not
change the default number of sections on the same page as any other number would.
A more appropriate check has been put in place.

This also incorporates a fix for MDL-28584. The course edit screen now also checks to see
if maxsections is set or numeric. If it is not set or numeric then it defaults to 52.
