Subtitle Renamer for PLEX

# Subtitle Renamer
# Written by No_MansLand on Reddit
#
# Bugs:
# - Renamed files are incorrect in the print out, not the actual export.
# - Copies the primary file for some reason.. I'll figure this out eventually.
# - No ISO-816 yet.. I'm planning on this.
# - Probably something else? I dont know..
# - Let me know.
