WE ARE TEAM ROCKET, YOU CANNOT BEAT US

- Adds a slightly remade version of the Rocket battle theme that plays when fighting Rocket Grunts, Jessie & James, and Giovanni (1 and 2)

- Giovanni 3 and Chief now share a new battle theme composed by myself and LuciShrimp, which is a slower, more intimidating remix of the regular Rocket fight theme.

- Gave Giovanni 3 his own trainer class, allowing for better AI routines and smarter move choices.

- Removed Giovanni's name from the Viridian City Gym statues to keep his identity a further secret. It also made more sense than in vanilla.

- Gave the postgame Morimoto fight a better selection of moves.
