[CGMZ] Preloader - Version Alpha R2

Hi all, today this plugin was updated to version AlphaR2!

This version adds some plugin commands to preload font, image, or audio files. Previously, this plugin preloaded everything at game start. However, sometimes you might not need everything you want to preload to be preloaded at that time. This now allows you to preload things as needed, which should cut down on how much you need to have preloaded on game start. Note that you should still be wary of preloading too many things.
