AC-689 no longer storing selected array in scope object. SelectionInit should be called before Search in controllers- Users had it in the wrong order. Added ability to override internal selected array in SelectionInit with reference to external array to support the groups page. Fixed cosmetic/styling differences between hosts and groups inventory pages.
