Added callbacks and new iconClass parameter.

[objectivehtml]

• Added two new callbacks, init() & changed()
• Added new option "iconClass", which will add another nested span tag with the defined classname. This makes working with icon fonts easier (like Font Awesome).

@objectivehtml I'm curious what the preferred method would be to populate the icon into the new span? Do you just use :before ? And if so, why do you need an addition span to do so?

I have all this working already. I need to recommit my changes so you can see all the stuff I did. I made a pull request, and then decided to refactor my work a bit. I think with these new callback methods and new params for the icon node, it works great.

I use Font Awesome for my icons. So I typically do something like this:

<i class="icon-search"></i>

or

<span class="icon-search"></span>

So with your plugin, I just added a param to append a new icon node and I could apply any class to it. I bet there were other ways to do it, but this was easiest/quickest for me to implement.

I just pushed my latest changes.

Here is a basic usage example:

(function($) {
    $(document).ready(function() {
        $('.custom-select').customSelect({
            iconClass: 'icon-sort-down'
        });
    });
}(jQuery));
