[CGMZ] Credits - Version 1.4.0

Hi all, today this plugin was updated to version 1.4.0!
This version adds a One Category mode to your credits window. When this is enabled, the Credits window will only display one category of credits at a time, with the player being able to cycle through categories by using the page up / down buttons. This should allow you to have an unlimited amount of credits, as previously you were limited to the max height of my scrolling windows which is somewhere around 16,000 pixels tall or around 150 credits which a few people have hit over the years.
See below gif for how it can look:
