Finishing Silph Co. 11F

That's a fair chunk out of my day...

This commit finishes everything about Silph Co. 11F. DON'T. TOUCH IT. Unless there's a bug, but OTHERWISE, do NOT touch it. Holy shit.

Here's everything featured;
- Jessie and James fight, ported over.
- Rocket grunt changed to the appointment one from the strange room on the other side that really shouldn't be there tbh
- Omega fight now doesn't have the "watch out" text as I needed to do a micro-optimisation TRUST ME it was NECESSARY (it was not, in fact, necessary)
- Giovanni now reuses Beedrill and has a generally stronger team, scaling with the fifth Rival fight.
- Omega refight has been added after some toiling with the Team Rocket intro text that absolutely should not have happened but did for some reason AAA
- Rocket trio text somewhat tweaked

Oh and I ported over the balance patch on the stats, including some neo-Cryithan onboarding.
