fixed problem with undo. regularized all linkfollowing anchor fields to start with followLink<xxx>. added ease vs linear flag for scroll transitions in link and preselmeent navigations. added link follow to move target to specified offset from source. shifted from setting dropAction on items to setting childDropAction on collections
