Items, Pickups and Powerups.

[oppotaku]

Add Items, Pickups and Powerups, that give the player a new move/ability, weapon or buff (or debuff). They can be spawned when you want (which one you want) in practice and are spawned randomly in stages if you enable the feature.

This already could be done via helpers.
A game-wide implementation could be made via attachedChar or commonStates.

In the future I could make a example implementation of this if you think is a good idea.
