Fix missing icon

I am using Ipython 2.3.1 and 'fa-share' isn't available. I guess it's because fa icons must be accessed with fa replaced by 'icon'.
But the icon i get by using 'icon-share' is not the same as 'fa-share'.
However i am sure the ipython I am using is using font-awesome, because it's custom.js default template has this bit:
 *                 'icon'    : 'icon-terminal', // select your icon from http://fortawesome.github.io/Font-Awesome/icons
So, is it just me, or is this a correct modification?
