This change adds support to M.core.dialogue for showing fullscreen
dialogs on small screen sizes. There are 2 new configuration values that
can be set to control this when creating a dialog (responsive and responsiveWidth).
Setting responsive to false will disable this functionality completely (old behaviour).
Setting responsiveWidth controls the screen width that the dialog will switch to
fullscreen mode. Try not to think of the device that will be accessing the dialog,
but the width at which the content of the dialog needs to be displayed differently.
The activity chooser and the filepicker are the two dialogs that have been converted
in this patch. The filepicker first had to be converted to use M.core.dialog and not
Y.Panel.
The following changes have been made:
* course_section_cm_edit_actions now allows the caller more options for the
display of the action menu.
* The site menu block now disables the JS enhancement of the actionmenu so
that it displays as it did before. After more testing this seemed like the
only option that worked in the limited space of the block when it had
several modules.
* draganddrop of resources now triggers the action menu enhancement as well.
* Fixed display of title when the menu is not being enhanced by JS.
* Fixed the alignment of the completion icon in the bootstrapbase theme.
* Tweaked the CSS for the standard theme.
This change adds keyboard support to core drag and drop.
Selecting a grab handle and hitting enter (or space) will
open a menu of possible drop targets and allow you to choose one.
The only other UI change this implies is we need to show the grab
for blocks.
* Fixed IE8 display of icons.
* Fixed blocks using course renderer.
* Fixed behat tests.
* codecheckers fixes
* Removed alt from icons with descriptive text
* Tweaked actionmenu initialisation for performance
