Title: Added a callback to select changes.

Currently there is no way to attach event handlers to select elements because of the way you dynamically create your own structure to display the select.

This callback adds this functionality through an alternative way, you can do:
$('#mySelect').material_select(myCallBackFunction);

Ofcourse, $('select').material_select(someFunction) wouldn't make sense since you would have a single function handling every select's change event, so you should just use this on a single element.

Accepting this pull request will not break any current code. Not passing in a callback simply doesn't fire it.
