/**
* Reference tooltips
*
* Adds a tooltip to references when hovering over or clicking them
* Based on [[mw:Reference tooltips]]
*
* @author Cqm
*
* @todo Add fade in/fade out animations for config form and tooltip
* @todo Find some way to detect of user has keyboard/mouse
* as windows 8 supports touchscreens and a mouse
* so allow hover activation if that's the case
