[CGMZ] Map Upgrade - Version Alpha R5

Hi all, today this plugin was updated to version AlphaR5!

This version adds more autoplay options for your BGM and BGS which can make it so your larger maps do not always play the exact same BGM and BGS. The player may spend quite a lot of time on some of your maps, or traverse some maps quite often, this can help make it so each time they are on the map it is slightly different and still feels new.

• Added option to pick from multiple autoplay BGMs / BGS
