RAFAEL_SOL_MAKER's VX AUDIOFILE ENTENSION v.1.0

#===============================================================================
#             RAFAEL_SOL_MAKER's VX AUDIOFILE ENTENSION v.1.0
#        (Include implementations from 'Audio Position' 1.0, by OriginalWij)
#-------------------------------------------------------------------------------
# Description:  Complements the audio functions adding some new routines like
#               'ME.last' e 'SE.last' to paly again the last effects ran
#               recently. This version contains implementations from
#               OriginalWij's script that adds the currently sound position
#               (eg.: BGM.position), it could be very useful for sincronizations
#               between then. In the future this script would be more powerful
#               and give more control over all the audio files of your game.
#-------------------------------------------------------------------------------
# How to Use:   Just put the command of your preference, like:
#                 my_var = RPG::BGS.position
#               OBS.: If the sound is repeating or if it's already finishied,
#               the total execution time (position) will continue to increment,
#               until you stop it, to reset the counter.
#-------------------------------------------------------------------------------
# Special Thanks: OriginalWij
