Auto-Unequip Tools for Falcao's ABS by Sixth

#===============================================================================
# * [ACE] Auto-Unequip Tools for Falcao's Pearl ABS Liquid v3
#===============================================================================
# * Made by: Sixth (www.rpgmakervxace.net, www.forums.rpgmakerweb.com)
# * Version: 1.3
# * Updated: 18/11/2016
# * Requires: Falcao's Pearl ABS Liquid v3
#-------------------------------------------------------------------------------
# * < Change Log >
#-------------------------------------------------------------------------------
# * Version 1.0 (06/01/2016)
#   - Initial release.
# * Version 1.1 (12/05/2016)
#   - Fixed the ammo display for auto-unequipped tools.
# * Version 1.2 (10/08/2016)
#   - Item tools did not unequip if another tool caused the party to lose the
#     item (by assigning an item cost for that tool). This is fixed now.
# * Version 1.3 (18/11/2016)
#   - Fixed a bug with unequipping tools.
#-------------------------------------------------------------------------------
# * < Description >
#-------------------------------------------------------------------------------
# * Tools which can not be used due to insufficient item or variable
#   requirements can be unequipped automatically with this script.
#   Note that the player will NOT be able to equip any of these tools after it
#   is unequipped automatically until the player got enough item/variable to
#   use them again!
# * The variable requirement mentioned above is from another ABS addon I made,
#   but it is not necessary for this script to work!
#-------------------------------------------------------------------------------
# * < Installation >
#-------------------------------------------------------------------------------
# * Place this scipt below the last script from Falcao's Pearl ABS Liquid v3
#   script series but above Main!
# * If you are using my Tool Variable Usage for Falcao's ABS script, you must
#   put this one below that one!
# * If you are using my Tool Cycler Addon for Falcao's ABS, you must put this
#   script below that one!
# * You can do an optional edit in the "Pearl Item Pop Up" script. This edit
#   will prevent the item gain popup when the tool is automatically equipped
#   due to this script. It's kinda annoying and looks bad to see that popup
#   everytime the tool is unequipped automatically.
#
#   Anyway, here is what you need to do:
#   Right at the start, after the settings part, you will see this method:
#
#~   alias falcaopearl_itempop_gain gain_item
#~   def gain_item(item, amount, include_equip = false)
#~     if !item_container(item.class).nil? && SceneManager.scene_is?(Scene_Map)
#~       if amount > 0
#~         $game_system.item_object = [item, amount]
#~         RPG::SE.new(PearlItemPop::ItemSe, 80).play rescue nil
#~       end
#~     end
#~     falcaopearl_itempop_gain(item, amount, include_equip = false)
#~   end
#
#   Replace that whole definition with the one below:
#
#~   alias falcaopearl_itempop_gain gain_item
#~   def gain_item(item, amount, include_equip = false)
#~     unless $game_system.disable_item_pop == true
#~       if !item_container(item.class).nil? && SceneManager.scene_is?(Scene_Map)
#~         if amount > 0
#~           $game_system.item_object = [item, amount]
#~           RPG::SE.new(PearlItemPop::ItemSe, 80).play rescue nil
#~         end
#~       end
#~     end
#~     falcaopearl_itempop_gain(item, amount, include_equip = false)
#~   end
#
#   I couldn't just overwrite it, because that would make compatibility issues
#   with many scripts, and I could not alias it in any way, because the popup
#   mechanic is already in it, so that would be called no matter how I alias it.
#
#   Simply copy the above method, and paste it over the old method, deleting
#   the old one in the process. After this, select the copied method and press
#   CTRL+Q while it's highlighted to remove the comment sings from it.
#   Do NOT remove the comment signs from this header!
#
#   I hope this little copy/paste job won't be hard to do for anyone. :P
