Correct ammo and charge messages for /k

[DayV-git]

Description:

Currently, for monster killing trips the message outputs ammo and charge usage that haven't been reduced by ava's / penny.

Updates messages to correct amount reduced. Also removes some of the charge message as it was too much clutter. Includes final message to confirm charges reduced by ghommal penny for monster killing and colo

Changes:

• Remove old charge use from \k messages, and instead add the message output from removing charge function.
• Shorted reduce charge message to just the number of charges used per item.
• Where applicable, add message for reduction from penny
• Update item costs based on the actual items removed from bank

Other checks:

• I have tested all my changes thoroughly.
