Temporarily ignoring the contents of the function, we do two very important
things in this code. We define the handler function and we register it with the global
event dispatcher.
Moving on to the guts of the plgSmileyButton() function, we will start by looking at
the $name parameter. This parameter is the name of the editor area.
