The client should not save the record when a button is clicked if it has a parent

(empty description)

added tryton type::behavior + 1 deleted label

Instead of calling save on the screen, we should call save of tryton/gui/window/form.py

added 1 deleted label and removed 1 deleted label

We can not call the save on form because if there is a invalid field on parent, the user will not see it (nor get focus).
Button should be active only if all the parent tree is not modified.
