Node editor changes :
	updated PM rules for each handler. updated initial (when a closed node is opened) starting cases for each widget.

Bugs :
	equation handler still not working completely
	0 value in initial is not working properly. Its not saved when you open the node again.
	if you have selected a type and closed a node, the border comes, so if after reopening a node u change the type to defaultSelect the visual goes really bad. - discuss with pradeep
