Bug 645390

The problems that keep cropping up with regard to multiple select behavior causing problems in any list (users, instances, templates, etc) are all related to one thing: we are using checkboxes to perform the task that a radio button is built for.  Namely, this release only supports acting on one object at a time, so there does not seem to be any reason to be doing all this extra work with javascript to try to shoehorn single select behavior into an element design for selecting multiple items.

Jakub agreed that if we are not supporting multi item actions at this point, radio buttons make more sense.  We can flip them back to checkboxes for the html fallback once we support acting on multiple items, but for now, this course is simply causing a steady stream of bugs, and should be reversed.

Please switch checkboxes to radio buttons on tables/lists that only support a single selection, and remove js if needed (if it doesn't cause issues, we might want to leave it for use/enhancement in next release).
