Make Dragon's Grip function like Blast Mine, and Head-on.

As a survivor, when you apply Blast Mine, or use Head-on, the ability is not used and does not go on cooldown if the killer was not affected in any way.

With Dragon's grip, if you apply it to a generator and it never fires in those 30 seconds, the perk still goes on cooldown and resets.

If a survivor doesn't interact with a generator that has had Dragon's Grip applied to it, allow the killer to retain the Dragon's Grip charge, until a survivor does interact with it.
