Bug 1102171 - [Usage][Refactoring] ViewManager.loadPanel should cleanup panels DOM once scripts/links are activated. r=salva

Unfortunately it's imposible to directly move/clone thise nodes to the head. As per :bz it won't work because script node cloned from one that was inserted via innerHTML is still "marked" as not-to-be-loaded-or-executed. So we'll need to create new script nodes anyway.
