Stone Evolution L1 Learnset Improvements

Because these Pokemon cannot be captured in the wild, this exclusively buffs the trainers, and by a significant amount too. I left Starmie out to balance out the early-game given how powerful it can be.

Ninetales should be at least L42 in each encounter to account for Fire Spin.

Vileplume and Bellossom should be at least L38, but I think Erika puts Mega Drain over Petal Dance so she should be fine..?

Tsubomitto should be L40+ to account for Lovely Kiss.

Exeggutor should be at least L48+ to account for Sleep Powder.

Cloyster should be at least L23 to account for Clamp. To nerf it, increase its level to 50, where Spike Cannon replaces Explosion.

I have also done a few fixes and stuff;
- Magnezone is part-Steel
- Leafeon gets Swords Dance
- Added Silph Gauntlet Team for the Channeler, assuming L65 is what will be used.
