[CGMZ] Battle BGM Control - Version Alpha R5

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

This version changes the enable switch so that if it is not set, the battle bgm changes will occur. Previously, not setting this switch in plugin params would cause default BGM behavior.

This update also allows this plugin to work better in battle test. It has a new parameter that will cause it to skip any switch conditions in battle test, so you can have an Enable Switch set but still hear your themes in your battle tests. Switch conditions for each theme are also skipped. Other conditions still apply.

• Enable Switch behavior changed
• This plugin now skips switches in battle test
