[CGMZ] Animated Battle Backs - Version Alpha R2

Hi all, today this plugin was updated to version AlphaR2!
This update makes it easier to control when the animations are shown in the battle background.
You can now have your animations start the battle hidden. There are also two new plugin commands: Show Animation and Hide Animation. These will allow you to show/hide an animation during the battle.
Animations now also have an opacity parameter, in case you want slightly transparent animations.
- Added opacity setting to animations
- Added plugin command to show/hide animations mid-battle
- Added option to have animations start hidden
