Subject: [REF] web, *: create jQuery ':hasVisibility' and ':hasOpacity'
 selectors

* web_editor, web_tour

jQuery has the built-in ':visible' selector. This is however not enough
as this only checks if the element and its parents have a visible
'display' property. Ironically, if the element has the 'visibility'
property set to 'hidden', it will be considered ':visible' by jQuery.

This commit creates the ':hasVisibility' and ':hasOpacity' selectors
which respectively check if the element and its parents have a visible
'visibility' property and a visible 'opacity' property.
