'We want to add the cmdset to the linked object.
Note that the RedButtonBlind cmdset is defined to completly
replace the other cmdsets on the stack while it is active
(this means that while blinded, only operations in this cmdset
will be possible for the player to perform). It is however
not persistent, so should there be a bug in it, we just need
to restart the server to clear out of it during development.'
