* Source/NSMenuView.m ([NSMenuView -trackWithEvent:]):

new tracking code. The menu feels snappier now (at least for me).

* Source/NSColorWell.m ([-activate:], [-deactivate])
  register/unregister for NSColorPanelColorChangedNotification.
  ([NSColorWell _takeColorFromPanel:]): new method to prevent endless
  loop when setting the well's color from the color panel.
  ([NSColorWell -initWithCoder:]): register for NSColorPboardType.

* Source/NSColorPanel.m ([NSColorPanel -_bottomWellAction:]):
  called when hitting one of the well at the bottom of the panel.
  Previous behaviour would not send a
  NSColorPanelColorChangedNotification.
  ([NSColorPanel -initWithCoder:]): update bottom wells construction to
  call _bottomWellAction: instead of takeColorFrom:.
