# Bank of Mom - By Vendily [v20]
#===============================================================================
# This script adds in the Bank of Mom Feature from GSC or HGSS, where
#  the player's mother will save money and occasionally buy items.
# The mom attempts to buy an item after the end of every battle, if she can
#  afford one of the MOM_FIXED_ITEMS or MOM_RANDOM_ITEMS.
# If she buys an item, she will call the player after the battle ends.
#===============================================================================
# Several additional, required edits in `def pbMessageDisplay` to add 
#  the `mgoldwindow` variable, to show how much money the Bank of Mom holds.
#  1. Under `goldwindow = nil`, put `mgoldwindow = nil`
#  2. In the long `while text` regex, add `mg|` before `g|`
#  3. Under:
#      when "g"      # Display gold window
#        goldwindow&.dispose
#        goldwindow = pbDisplayGoldWindow(msgwindow)
#     Put:
#       when "mg"    # Display mom gold window
#         mgoldwindow&.dispose
#         mgoldwindow = pbDisplayMomGoldWindow(msgwindow, goldwindow)
#  4. Under `goldwindow&.dispose`, put `mgoldwindow&.dispose`
# These edits may have to be made to a plugin if one overrides this method.
#===============================================================================
# Some neat details.
#  - The mom can save 1/4, 1/2 or all the money the player wins in battle.
#     This is set by the player. This does not affect earnings from Pay Day.
#  - pbMomManageBank allows the player to withdraw, deposit, or change the
#     amount saved, or cancel saving altogether.
#  - The mom still spends money even if the player is not saving anymore.
#  - The mom defaults to not saving any money.
