Proximity Wraparound fix

MAJOR BUG: This patch causes Bouncin' Chucks to make shell-less koopas near them constantly turn to the right (to the point they will wiggle through solid objects/sprites!) while the Chuck is idle. It's easily and consistently reproducible and a big problem because these are standard sprites.

Tested on an SA-1 rom with no other patches applied, so it's definitely this patch doing it.

Fixed a small oversight that caused jumping Piranha Plants to always jump regardless of player proximity. Also added FastROM mirrors and removed a handful of redundant org commands for improved readability/Hijack Map alignment.

It simultaneously does and does not amaze me that this is a problem that even needs fixing. Either way, this patch does the trick, making proximity-based enemies behave a great deal more consistently (especially Rip Van Fish, what with the extra dimension of movement provided by water levels). If there’s ever another update to this patch in the future, it would be neat if all of the constant proximity values would be converted into defines - this patch would then be especially easy to use as an enemy proximity detection range changer.

Added changelog so you know what's changed in new versions (though you can already see what from description).

Ground-Dwelling Monty Moles have this issue and aren't fixed by this patch. Ran into this while designing a level just now.

Decided to check the other Monty Mole enemy as well, it also has this same issue.

Worked fine. Tested in horizontal levels (normal and big levels), vertical levels, lorom and sa-1. Accepted.

Optimized and added fixes for Swooper Bat and Exploding Blocks.

Too bad it doesn't fixes exploding blocks and other sprites I forgot about

This patch is good for people that don't want certain sprites from acting weird should the player be at the boundaries of the screen, making the sprite checks go crazy.

Do note that custom sprites are not affected by this. Therefore, use the subroutine in this asm file instead.

You mean the original proximity check on the asm library? Although, I didn't intentionally steal his code, I wrote this patch from scratch, must be a coincidence then.

Well, the JSLs for SubHorizPos16Bit and SubVertPos16Bit have been converted to JSR in order to save a bit of time and space. Also, this code was made by Sonikku.
