RDM QoL change: Impact should overwrite the Jolt II hotkey when it procs.

[Luphy1201]

And for this you lose the ability to queue, and Impact will typically be skipped over, straight to Jolt, if within a minimum wait period (1 second) of a previous command.

I tried it all the way to 70, works fine with macro, just grey out impact icon replacing jolt icon so you know that impact is been proc.
