Carving: object/background shortcut tooltips are updated.
SplitBodyCarving: When 'deleting' the current fragment, explicitly clear the current seeds if the fragment was never saved.
(If the fragment was previously saved, the seeds are cleared automatically.)
SplitBodyCarving: "Activate 3D View" checkbox is checked by default.
SplitBodyCarving: Added shortcut for toggling the raw data position in the layerstack.
