Java PVP scoreboard fix

This is basically just a combination of Blurry's Java PVP and Beyond's Java PVP that fixes the scoreboard stuttering glitch.

More specifically, this uses the attack indicator animation from Beyond's and the swinging animations for each weapon from Blurry's. Together this makes the ultimate Java PVP addon that doesnt suffer from the scoreboard flicker glitch, making for the perfect survival/SMP/PVP server on bedrock edition.

REQUIRED BETA APIS
MAKE SURE THE BP AND RP ARE BELOW WHATEVER SCOREBOARD ADDON YOU'RE USING OR ELSE IT'LL BE BUGGED
