Change PCBNew and CVPCB 3D viewer focus behavior. (fixes lp:818890)

* Raise 3D frame in PCB editor and module editor instead of displaying a message
  dialog indicating that the 3D viewer is already open.
* Raise 3D viewer and module viewer in CVPCB to mimic the behavior changed in
  PCBNew.
* Set focus to OpenGL canvas when creating 3D viewer so mouse wheel events
  are handled on Windows without having to click on the canvas.
* Rename 3D viewer frame class from WinEDA3D_DrawFrame to EDA_3D_FRAME.
* The usual smattering of coding policy fixes.
