MDL-37828 theme_base: Removed old CSS for popuphelp in style/core.css
MDL-37886 behat: Prevent dropping test site when running tests
MDL-37654 core_course: ensure exceptions return static error codes for debugging purposes
MDL-37883 Assign offline marking: Properly handle french decimal grades when importing worksheet.
MDL-37122 core get_max_upload_sizes: Include "Course/Site/Activity limit (X)" in list of options

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).

MDL-30637 Simplify moodle forms

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');
MDL-30638 mod_choice: Add required elements to repeated form items

To make it work properly with MDL-30637
MDL-30637 mod_folder: Make content section expanded

This just makes the interface better
MDL-30637 mod_resource: Make content section expanded

This just makes the interface look better
MDL-30637 backup: Disable shortforms for backup interface

As all sections requre user attention or input, there is no sense making them
collapsed in backing up interface.
MDL-30637 Refactor Advanced fileds functionality

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
