Muddle/Smoke Bomb fix

EDIT: Added an Imp's Rage-compatible version of the patch.

Hey, everybody, this year is off to a good start, hacking wise! Here's a patch for a long-standing exploit (only recently fixed in the Mobile/Steam releases). I'll just copy from the readme:

Casting Muddle on one of your characters and then having them select an attack causes the targeting on that attack to be reversed - even with attacks that can normally only target characters. This behaviour is a wellspring of bugs and exploits; for example, the disappearance bug associated with getting hit with Muddle during a Palidor cast, or shenanigans such as using Smoke Bombs on enemies to cause them to run away.

While assassin17 released a patch for the Palidor issue long ago, the exploit of using Muddle to reverse the targeting on Smoke Bomb or other character-only attacks was never addressed until the PC/Mobile remakes.

This patch neatly fixes all Muddle-related targeting bugs by simply canceling any attack someone may have queued up when they are hit with (or cured from) Muddle, much in the same way Sleep does.

Apologies to all lazy Intangir farmers and low-level Charm Bangle enthusiasts.

Introduction:
   Casting Muddle on one of your characters and then having them select an
   attack causes the targeting on that attack to be reversed - even with
   attacks that can normally only target characters. This behaviour is a
   wellspring of bugs and exploits; for example, the disappearance bug
   associated with getting hit with Muddle during a Palidor cast, or
   shenanigans such as using Smoke Bombs on enemies to cause them to run away.

   While assassin17 released a patch for the Palidor issue long ago, the
   exploit of using Muddle to reverse the targeting on Smoke Bomb or other
   character-only attacks was never addressed until the PC/Mobile remakes.

   This patch neatly fixes all Muddle-related targeting bugs by simply
   canceling any attack someone may have queued up when they are hit with (or
   cured from) Muddle, much in the same way Sleep does.

   Apologies to all lazy Intangir farmers and low-level Charm Bangle
