Changes

Show whether a GameObject is active
Adds an A:True/False indicator to each game object which says whether
it's active (note - this is whether the game object itself is active,
not whether it's active in the hierarchy which depends on the parents)
 (commit: 0625aff)

Add toggle to show active/all GOs
If the switch is set to active and a GameObject is not active in the
hierarchy, none of its component indicators will be rendered.  Note that
everything is still shown in the hiearchy list.
