Finish missile launcher implementation

[MayberryZoom]

Marking this as a draft as currently Storm Missiles are visually chargeable without Missile Launcher. They can't be shot, but removing this visual bug would be nice. If we can't find a way to do it and think it's okay to work this way, I'll mark this as ready for review.

Fixes #342

we have a launcher model already, which is great, but we'll need to add a map icon as well

I pushed what I have for now, but I just noticed that the Missiles are taking priority over Supers/Ice for some reason. Checking the inventory, I had ITEM_WEAPON_SUPER_MISSILE, ITEM_WEAPON_ICE_MISSILE, and ITEM_WEAPON_SUPER_ICE_MISSILE but still shot normal missiles. No idea why, the priorities in samus.bmsad look correct to me.
