[mdt-papyrus.dev] [sashEditor] SashEditor should run on both 3.8 and 4.x

[Cedric Dumoulin <cedric.dumoulin@xxxxxxx>]

  Hi all,

  I have provided a solution for the  bug:
370744: [sashEditor] SashEditor should run on both 3.8 and 4.x
https://bugs.eclipse.org/bugs/show_bug.cgi?id=370744

Now the code run on both 3.8 and 4.2, but it compile only on 4.2.

  It is possible to let it compile on 3.8 (but in this case it will not 
run on 4.2) by simply commenting some faulty lines in
org.eclipse.papyrus.infra.core.sasheditor.internal.EditorPart.createSite(IEditorPart)
This is documented in the class.

  The provided solution is not temporary.
  Hope this help,

  Cedric
