6th Gen move fixes + ORAS stuff

Primal Reversion message
Adds freeze to Freeze Dry and burn to Steam Eruption
Adds attack drop chance to Play Rough
Fixes error in Pulsing flag with Mega Launcher, renamed the flag as a result to prevent future confusion (Moves like Aerial Ace were boosted with Mega Launcher, not an urgent bug because you need Skill Swap/etc. to even find it... Or adding a flag to Dragon Ascent would do it too.)
Adds FarReachFlag to Flying Press, Oblivion Wing, and Dragon Ascent
Block the 4 new moves in Metronome
Add effects for Hyperspace Fury
