Message:

Added Dragger::s/getActivationModKeyMask(..) and Dragger::s/getActivationKeyEvent(...) methods to make it possible to have draggers that only respond when you press a specified modified key or standard key.

Changed the optional dragger in osgvolume to require the shift key to be pressed for the dragger to become active.
