Version 2.63 minor bugfix

Good morning RPGMakers.

I have uploaded version 2.63 of the Dual Wield plugin, which corrected the following issue:

• Damage formulas which reference a.atk or user.atk multiple times will no longer only replace the first instance a.atk or user.atk in the formula with the calculated main or off hand values, and will now correctly replace all instances of those strings.
  • This was causing unexpected high damage output on skills being used by dual wielding actors, as any subsequent uses of 'a.atk' in the formula were taking attack values from both weapons, instead of only the current one.

This bug has existed since the version 2 rewrite of this plugin. It took the keen eye of user Grunwave from the RPGMakerweb forums to find this one. Thanks Grunwave!
