[XP Script] Audio Module Rewrite mcisendstring

The Patch
Due credit to find the issue goes to Geminil. Give him due credit as well.
Code:
#==============================================================================

# ** Vehicle SendString Patch  v 2

#------------------------------------------------------------------------------

#  PLACE MCISendString above the Vehicles System Files.  Then place this

#  patch below both systems.  It overwrites certain features from Vehicles.

#

#  IMPORTANT:  BGS Sound Playback is affected.  BGS audio files MUST be in

#  your project's Audio\BGS folder and cannot have the same filename as any

#  RTP file.  You may copy '001-Wave01' into your project, but name it some-

#  thing else insteadl.

# ** Game_Player

#------------------------------------------------------------------------------

#  This class handles the player. Its functions include event starting

#  determinants and map scrolling. Refer to "$game_player" for the one

#  instance of this class.
