Added fix for #6 by @DiegoPires.
fix #16: Updated to Select2 v3.4 and corrected readonly syntax
fix(tests): Adjusted tests to pass properly
Added destroy handler to remove the select2 when the parent element is removed from DOM

If I have <select ui-if='some-condition' ui-select2 ... ></select>, when some-condition is false, the select2 generated artifact is left behind. I am not sure if there is a better way that doing this in a $destroy handler or I am doing my code the wrong way. - Thx
refac: ng-model is now required

There is no real purpose in using select2 without an `ng-model` so I'm simply going to make it required and remove the conditional code.
