Partial implementation of infinite widget recursion protection; some cleanup. Implemented recursion protection which only allowed unsafe widgets to be instantiated once; realised this was far too restrictive (multiple sibling instances are needed) and a check against parent widgets would be needed. Could be implemented by passing widgets a reference to parents. Removed ButtonWidget aka First interactible widget.
