Title: radioButtonList crashes when argument $select is supplied as an array of selected elements.

Up to now it could only accept a single checkbox value.

However, when supplying array of selected element, it would throw error:
"strcmp() expects parameter 2 to be string, array given"

Now it evaluates correctly just like checkBoxList.
