Objectives: * Associate models with tools, rather than dialogs and inspectors * Move tool/model association utilities to ve.ui.ToolFactory * Obliterate the view registry Notes: The only special case for leaving modelClasses definitions in place is for the linkInspector. It uses these for selection expansion. Because tools can now override the static canEditModel method, we can dynamically evaluate a model, rather than be restricted to only comparing classes. This will be useful for disabling editors for models that are for some reason incomplete or otherwise broken and cannot be safely edited. Change-Id: I7adf254990112d90f1f808593a9111afc7a116b5
