Port powerups from the custom powerups patch

[TheLX5]

By no means I'll port every single powerup from the original patch, it's going to be horrible. I'll pick a few which will be provided as a separate download, bringing back the powerup as addons mentality from the custom powerups patch v2.0.0

Powerups to be ported:

• [ ] SMB3 Super Leaf
• [ ] SMB3 Hammer Suit
• [ ] Custom Boomerang Suit
• [ ] NSMB Mini Mushroom
• [ ] NSMB Shell Suit
• [ ] NSMBWii Ice Flower
• [ ] SMG Cloud Flower
