Commit of new FMD3 geometry and other geometry related issues.

- The FMD3 geometry is defined as per the final drawings of
  that sub-detector.  See also http://fmd.nbi.dk/fmd/drawings/.

  - No more any detectable overlaps with ITS.
  - Overlaps _are_ present by not found by automatic tools in ROOT.
    - It seems that there's a misunderstanding between ITS and FMD.
      The FMD3 flanges are sitting at 45, 135, 225, and 315 degrees,
      but ITS has stuff there.
    - I've put in the precision holes that aligns the FMD3 with the
      ITS.  If the ITS will implement in their geometry similar holes
      or spikes, then we can use these to determine what is wrong.

Also in this commit:

  - FMD2 moved back 2.5cm to avoid overlaps.
    - When I get the drawings of FMD2 I will check if this is real.
