Graph Editor: Visibility toggles improved (Durian Request)

Toggling one of the visibility toggles in the Graph Editor now flushes the new value up/down the hierarchy.
- when enabling a visibility toggle, all the 'higher' up and lower down channels get their visibility turned on
- when disabling a visibility toggle, only the ones lower down get their visibility turned off (since there might still be other channels at the same level which are still enabled.

This makes showing/hiding groups of F-Curves much easier, since previously you'd have to use multiple clicks to isolate particular F-Curves. For example, to isolate only X Location curves, previously, the workflow would have been to select all AKEY, hide all VKEY, then toggle the individual X Location curves in group, then make sure the groups and objects, etc. were also visible. Now, the steps of making sure that the parents were visible too has been eliminated.

Also, fixed a few minor bugs with the animation-backend code for Graph Editor.
