refactor: compare widgets via the .ptr memeber instead of via their addresses

Browse source 
Widget is a handle type. Sort of a smart pointer. Comparing their addresses
is brittle because it requires keeping Widget pointers stable. This is
nonsense because Widget identity is actually determined by the actual
widget object it points to.

This big refactor elimits the requirement that Widget addresses remain
stable to work properly with Widget.walk and Widget.get.
