Make it so you can't force people to touch borging artifacts

[Zamujasa]

Borg artifacts are now one of the limited ways to revive players in the event cloning is trashed. Outright removing this feature is a bit much, though I agree it could use some tweaking to not be a weapon.

For the record, you should need an aggressive (second-stage) grab to force people to use it. A passive grab (one click) won't do it.
