MDL-41041 portfolio: Temporary solution for event portfolio_send

As we have deprecated events_trigger(), the portfolio cannot use it
any more. Though there is no easy solution to get rid of this event
as it is used to register a cron job. MDL-42541 has been raised to
refactor the portfolio code to solve this problem. In the meantime
events_trigger_legacy() will be used.

MDL-42351 EditPDF: Fix jiggling of relatively positioned elements

When calling setX/setY with YUI - YUI takes into account the position style
of the element. If none is set it assumes position relative. Position relative
is bad because relatively positioned elements still take up space in the page,
and all the elements after that node are positioned, taking into account the size
of that node. So when a node is resized or deleted, all nodes after that one in
the list of drawables are affected.

The magic fix - is just to set position: absolute on the drawables before calling setX/setY.
