Add edit_order property to ERP5Form, that allows to define in which order the

setters for some properties of the form should be called by edit().

This is usefull, for example, when property A acquires its default value from
property B, and both are editable in the same form. We don't want A to be set
to B's old value when the user changes B's value and A had no value set.
