* When looking for texts inside the page or inside
other containers we should wait until the elements
are visible.
* Same when expanding tree nodes.
* Normalizing loops to spin() function using
behat_base::TIMEOUT and behat_base::EXTENDED_TIMEOUT,
leaving TIMEOUT for DOM load processes and
EXTENDED_TIMEOUT for long processes that involves JS
too.
* Add page load waits between actions that involves
reloading the page.
In general aiming for compatibility with multiple browsers,
firefox, chrome and phantomjs to be more specific.
* Removing hardcoded waits
* Adding @_alert, @_switch_window and @_switch_frame tags,
to label actions that different drivers have problems with.
* Adding missing @_files_upload and @_only_local tags to features that
uploads files.
* Fixing a few wait for page ready what specified miliseconds.
* New methods to ensure elements (usual selectors), sections and editors
are ready to interact with
* Changing the select an option implementation to deal with the different
drivers implementations when listening to JS events.
When a course format does not support AJAX, or AJAX is disabled at the site
level, we should revert back to the old-style move icon.
This helps to clarify that you cannot drag/drop the icon, but must click
instead.
Making a quiz visible on the course page, of via the settings form,
could cause the grade item to become visible in the gradebook, even
though the quiz supports FEATURE_CONTROLS_GRADE_VISIBILITY to ensure
that when the grades are hidden in the quiz settings, they do not appear
in the gradebook.
Now, if a module supports FEATURE_CONTROLS_GRADE_VISIBILITY, then
set_coursemodule_visible calls the _grade_item_update callback to update
the grade item(s).
In addition, there was a bug when saving the quiz form, where it used
the value of $cm->visible from the database, which was wrong if the
value of cm->visible had just been changed on the setting form.
On course view manage page, JS was not getting initalised as category-listing
is not visible, initialiseCourses is doing unnessary check for category as
it takes care of empty category so it should not return on empty category
* Drag and drop icon switched to a 12x12px icon.
* Drag and drop icon now uses cursor:pointer
* Improved alignment of the caret for course listing actions.
