now can edit items with double click-Sean

Need to review Matt's syntax for where to put the event handlers, so
study!!
edit with dbl click no placeholder on the clones

Changing attributes with event handlers to remove a placeholder on my
cloned items. Allow editing with double click, but wil not go readonly
afterwards yet
syntax tests for readonly addback-not working

trying to figure out how to add back the readonly attriute on the edited
item being left. once changed back to editable, remains that way.
try to style the checkbox

not effective yet
edit task readonly added to ALL

need to somehow separate the first item, from both the checkox and the
readonly attribute
