[FIX] actions for the icon set icons were not working. 
Notes: currently icon set icons won't work if the parent element is <a> and the {icon} function has a title="" or a href="" parameter. This is because currently, if a title or a href parameter is added inside the {icon} function, than an <a> element is generated, so it ends up having <a> nested in another <a> element.
Currently one way is to include href and title param in the {icon}. The other way is to have a parent <a> element in the tpl, and only set the name parameter in the {icon} function. Although both can work, there was a discussion on dev list to include as few html in smarty tpl-s as possible, so I guess the first way should be used where possible.
