Apply Object Transform: Multi-user data support
The current behaviour is to prevent multi-user data from having its
transformation applied.
However in some particular cases it is possible to apply them:
* If all the users of the multi-user data are part of the selection.
* If not all the users are in the selection but the selection is made
single-user.
The active object is used as reference to set the transformation of the
other selected objects.
Note: For simplicity sake, this new behaviour is only available if all
the selection is using the same data.
