multiselect 5.x-2.0-beta

A lot of changes here.

If the add/remove buttons are not visible with this release, please try the dev branch, if it's not up yet, it'll be up shortly.

Performance of populating very large lists of nodes to reference is now server-side. This should be much faster. I would especially appreciate users who experienced slowdown with an older version to test this.

The widget is now in a fieldset, so be aware that it will probably look different in your theme. Make sure it looks OK after upgrading.

Previously referenced nodes were always ordered by their NID, regardless of how you entered them in the form. Now nodes will maintain the order shown in the widget.

Much love to testers with feedback.
