@plugindesc Replaces save game titles with chapter / map names

@help
The default RPGMaker save files have a title that is the same as the name
of the game. While this may be classic PS1 memory card nostalgia, You may
prefer to have titles that show the player where the save file is in the game.

This plugin makes the save file title a combination of chapter number,
chapter title, and/or map name.

Setup:
To use chapters, you will need to reserve one of your game variables to
be the chapter number. This is configured in the plugin parameters, and
You will change the variable as needed using standard event commands.

To use chapter titles, configure the chapter names in the plugin parameters.
The first entry is for chapter 0, since variables are set to 0 at the start
of a new game.

To use map names, give each of your maps a display name in the editor.

Any elements of the save title can be disabled in the plugin parameters if
You do not want them.
