- Fixed flipped orientation of getViewViewvector(), was opposite in ortho

versus perspective.
  Note for Martin; still an issue with defining what positive/negative
  rotation is in perspective... needs more math here!
- Added Transform Widgets for PoseMode
- made adding bones in EditMode setting G.moving, so it doesn't draw other
  selected objects nor Widgets

Warning in commit of Martin yesterday: Trackball and initTrackball were
declared static, whilst also in transform.h. Quez; why are these functions
exported in the .h file?
