[CGMZ] Message System - Version Alpha R2

Hi all, today this plugin was updated to version AlphaR2!
This update adds a new text code for displaying a random text out of given options. You can use it by typing \rand[x|y|z], and the plugin will randomly choose between x, y, or z to display!
This update also adds a few plugin commands for some control over the message window. You can now change the message window windowskin and windowskin tone by plugin command, so you don't need to always type those text codes in each show text command. Hopefully this will cut down on some text codes in your messages.
- Added text code to display random text
- Added plugin command to change message window tone
- Added plugin command to change message windowskin
