[CGMZ] Idle - Beta Release

Hi all, today this plugin was updated to version Beta!
This version adds some stat tracking for total time spent idle throughout the game. It also adds a plugin command to get this new statistic. I plan to also add this as a potential stat you can display in the [CGMZ] Extra Stats statistics scene as well.
- Added tracking of total idle time throughout game
- Added plugin command to get total idle time
