Save / Load Option ~ RGSS2

#-----=====-----=====-----=====-----=====-----=====-----=====-----=====-----====
#           Save or Load?
#           Author: DP3
#           Update: HungrySnake
#-----=====-----=====-----=====-----=====-----=====-----=====-----=====-----====
#   Description:
#
#       This script will allow you to both save and load in-game.
#       No longer will you have to return to the title screen to
#       load up another save file.
#
#       Update: Made compatible with most of the other saving systems
#-----=====-----=====-----=====-----=====-----=====-----=====-----=====-----====
#   Instructions:
#
#     - This script is plug and play, all you have to do is go into
#       your database and change the vocab for save to something like
#       "Save/Load"
#
#
#     - Paste this script BELOW any other script which modifies the save system
#         (ie. Neo Save System or anything else)
#
#
#     - The script will give a command prompt when the save/load option
#       on the menu is selected.
