slowly getting the tree node model decoupled from being passed in to menu actions, updated more of the appState and clarified a few things, created a new umboptionsmenu directive to be used for the options drop down on editors
made syncTree method on handler return a promise so we can do somethnig with it after (it still raises an event). Updates all editors to assign a currentNode to their scope when syncTree is complete, now that gets assigned to the umboptions which is now decoupled from nav.ui.
fixes merge
remove sort controller's and views - when we put these back we can restore.
Nearly got the whole nav.ui stuff taken care of, have most of the correct objects in appState, fixed up tree syncing with move dialog, fixed up state handling of the currently selected node, removed setting the navigationController's scope from within the navigationService (?), still some more stuff to clean up.
fixes tree sync on move
fixes tree sync with move media/content
fixes: U4-3429 After sorting the tree doesn't get refreshed (for content)
no more nav.ui. removes exposing the userDialog, moves enter/leave tree to the navigation controller since it doesn't belong on the service, cleans up more of the nav ctrl and we have no more globals :) now to look at changing the object that is passed to dialogs (i.e. not the navigation controller scope)
