RAFAEL_SOL_MAKER's VX GENERAL SCRIPT EVALUATOR v1.0a

#===============================================================================
#            RAFAEL_SOL_MAKER's VX GENERAL SCRIPT EVALUATOR v1.0a
#          Based on 'Detailled Call Script Error Message' by ERZVX.
#-------------------------------------------------------------------------------
# Description:  Check all scripts generated "by the game", like the "Run Script"
#               event commmand, event move routes, or even event conditions.
#               It will act as a error handling and will provide a more detailed
#               error information, like error line, event that caused the error,
#               description, etc.
#-------------------------------------------------------------------------------
# How to Use: Configure in the general configuration module the use (or not!)
#             of this funcion.
#-------------------------------------------------------------------------------
# Special Thanks: ERZVX

# UPDATES
#-------------------------------------------------------------------------------
# VX GENERAL SCRIPT EVALUATOR -> v1.0a
# * In this revision, only the 'eval' scripts with a unique argument, like the
#   ones generated "by the game" will pass in this basic error handling. Anyway,
#   it's only recommendable to use after freeing the bugs of the scripts from
#   'Script Editor', since very few scripts yet can use the command internally.
# * Now the line with error is shown correctly in the message, even if the ran
#   script have only one line.
# * Some other minor things...
