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
