Adding move to trash action; making the root entity node refreshable.
add children entities to the view as they get loaded (instead of having them show up all at once)
Merge branch 'master' of https://github.com/fierarul/ovation-ui2
merged emilians entity trashing branch, and updated EntityChildren to sort node children as they appear
removed authenticating... progresshandle, but didn't get it to display after login screen and before nodes are loaded
