Item-passable blocks

I built some blocks that can be passed through, when you have a specific item on (i.e., enabled in the pause screen). It's somewhat limited... I wanted to get something done before getting it perfect, so I went with Air Fool XRay + BTS $0E for this and there's no extra code for shots/enemies/PLMs. Just Samus collisions.

ASM for xkas v06 and v14.

Addendum: the item I used in the code is HiJump boots, but you're expected to change that. If you find any bugs, PM me.
