The displaying of advanced items has been refactored. The changes are:
* The Advanced button is replaced by the Show Less/More link
* The Show less/more link controls advanced elements only within the section
it is located at
* The Show less/more state of sections is preserved between form submissions
* When javascript is off, all advanced elements will be displayed by default,
no show/hide controls will exists on the page
Make the forms easier to use and navigate by adding functionality to
collapse and extend form sections (headers). The logic is as follows:
If form contains 2 and less sections (headers):
* Display the form as non-collapsible at all.
* The point above can be overridden if developer marks the section as expanded
in form definition (e.g. $mform->setExpanded('foo'));
If form contains 3 and more sections (headers):
* always expanding the first section and closing all others by default;
* always expanding a section containing at least one "required" element;
* expanding any section which contains validation errors after submission;
* expanding any section which was previously open on previous submit (e.g. when
adding new choices);
* expanding the section which is marked as expanded in form definition (e.g.
$mform->setExpanded('foo');
This change removes the "0 bytes" option from the get_max_upload_sizes list
and replaces it with "Course limit (X)" or "Site limit (X)" (whichever is smaller).
This means we can remove all custom handling in the modules that were removing and
adding these options. It only affects pages that pass valid options for sitelimit and
courselimit - so admin pages will work correctly.
It also orders the list so the course/site limit options will be first
(as it will be the largest).

REM [courseuploadlimit, core] has been parameterized to get [uploadlimitwithsize, core]

If we set height as well as max-height then there is a potential for
whitespace to be shown at the bottom of the list of choices.
This commit stops removing the height option so that we only rely upon
max-height for dialogue heigh calculation.
Switching between categories view and edit no longer depend on global editing mode
/course/index.php and /course/category.php do not contain editing code
