Checked in migration from osgUtil based GUIAdapter code to Neil Salter's

Browse Source 
osgGA (Gui Abstraction).  This may break users code, but all it should
require to fix the builds should be a change from
osgUtil::CameraManipulator (etc) to osgGA::CameraManipulator and
include <osgUtil/CameraManipulator (etc) to osgGA/CameraManipulator and
the extra dependency of the link line.

/** Pure virtual base class for adapting the GUI actions requested by CameraManipulators

* There are several was of using the ActionAdapter either inheriting it as
* done with osgGLUT::Viewer class or passing a simple struct to the camera
* manipulator then unpacking the results and working out what to do to respond
* to the requests.
*
* Also there are several ways to run your app and handle the updating of
* the window. osgGLUT::Viewer always has a idle callback registered which does a
* redraw all the time. osgGLUT::Viewer can safely ignore both requestRedraw() and
* requestContinousUpdate() as these are happening all the time anyway.
*
* Other apps will probably want to respond to the requestRedraw() and
* requestContinousUpdate(bool) and again there is more than one way to handle it.
* You can override requestRedraw() and implement to call your own window
* redraw straight away. Or you can implement so that a flag is set and
* then you then respond the flag being set in your own leisure.
*
* requestContinousUpdate(bool) is for enabling a throw or idle
* callback to be requested by the camera manipulator. Again you can respond
* to this immediately by registering a idle callback or a timed callback, or
* you can delay setting the callback and do at you own leisure.
*
* requestWarpPointer(int,int) is requesting a respositioning of a mouse pointer
* to a specified x,y location on the window. Used by some camera manipulators
* to initialize the mouse pointer when mouse position relative to a controls
* neutral mouse position is required, i.e when mimicking a aircrafts joystick.
