Manage move of empty papyrus resources
This commit introduces a papyrus-specific mechanism to allow empty model resources to be merged simultaneously with non-empty associated resources. This is useful to maintain in sync *.uml, *.notation and *.di files. Change-Id: I7d709981d31046ef73a3feb50da2ae945fac267f Signed-off-by: Laurent Delaigue <laurent.delaigue@obeo.fr>
