Title: Added a refresh method.

I needed the refresh method because when using the multiselect widget in a tabbed view the original tab is hidden and therefore has no width. So on the tab change I needed to reset the dimensions of the multiselect. So I converted the set dimensions logic to one method _setDimensions then call this method in the _create and refresh methods.
