[CGMZ] Debug - Version Beta R6

Hi all, today this plugin was updated to version BetaR6!
This update added a CGMZ debug command which will open up a new command window with debug functions specific to certain [CGMZ] plugins. Currently, this is limited to [CGMZ] Achievements. If you are using [CGMZ] Achievements, you can view your achievements in the debug scene and toggle their earned/failed status. This should hopefully help you test your achievements without needing to actually complete them.
Here is a gif of how it looks:
This update also removed some older deprecated code calls to [CGMZ] Core functions.
- Added CGMZ debug command
- Added CGMZ Achievements debug commands
- Removed deprecated code from [CGMZ] Core
