fix for glitches with quad-split view.

- Home or Numpad Period with smoothview disabled were not syncing up the other views.
- Disabling clip only disabled clip syncing but left clip enabled for all views.
- Clip was being calculated for every update even when not enabled.
- The perspective view was being used to copy settings from when changing box & clip settings, resetting the distance each time. Now use one of the aligned views instead.
