Before this patch behat_dataroot for parallel runs
were created at same level as ->behat_dataroot
After this patch, it will be created 1 level under
->behat_dataroot with BEHAT_PARALLEL_SITE_NAME
prefix and run number as suffix. This will allow
common files as test enabled and parallel run info
to be saved in parent directory and access it easily.

This improvement prevents refresh of SCORM 1.2 navigation menu
when the navigation menu is not displayed.

Thanks to Leandro for providing a fix

Added role and aria-expanded attributes to the toggler link and added
a key handler for the space and enter keys.

Converting the uses to the AMD modules is a bit risky for now, instead
just require the YUI depdency.

get('blah') are for properties
get_blah() are for helpers
