[RGSS] NEED TO REFERENCE MAP DATABASE NAME, NOT MAP DISPLAY NAME.

Hey guys. Here's a small snippet from a script I'm using that calls the map's display name and writes it on the screen.

Script in question: http://pastebin.com/uwLJzta3

This is Moghunter's save/load screen script, which writes your location on the save screen. The script draws it from the map's display name, but I want it to use a map's database name in the map tree. I want it to use the map name in the database/map tree (so just the actual map name itself). Anyone know what I need to change in the script to make that happen?
