- Created a MoveManager than now handles move methods. - MoveTool and SelectTool now use the MoveManager. - Blender like move now use a camera aligned plane to move along so things are more "blenderish" - One can enter move/rotate/scale values with the numpad git-svn-id: https://jmonkeyengine.googlecode.com/svn/trunk@9604 75d07b2b-3a1a-0410-a2c5-0572b91ccdca3.0
