[CGMZ] Actor Upgrade - Version Alpha R7

Hi all, today this plugin was updated to version AlphaR7!
This version focuses on actor levels, both pre- and post-99. Post 99, you can now have an easier time creating stat values instead of needing to hard-code them all which may be tedious if you have a lot of levels beyond level 99. You can use either a flat increase for each level, or you can type your own JS formula in.
You can also control the actor's max level now, including pre-99 levels. This is done via the Max Level Variable parameter, where if set it will use the value stored in that variable as the actor's max level. You can use this to control how high level an actor can get, in case you want to prevent the player from grinding to get too high level.
As part of this, I also added a simple boolean parameter to determine if actors can still gain experience if they are already at max level.
- Added formulas for post level 99 stat values
- Added option to control max level by variable
- Added option to prevent exp gain at max level
