Change move folder form to not have default radio btn and to show hint

Updated the move folder form to add a hint for the radio button for the
current folder saying 'current folder'. This hint does not get shown if
you are viewing all folders (so you are not inside a folder).

Also stopped a default radio button from being selected on the form.
