Prevent lag on close menu for RMMV

This small plugin is for RMMV.

It prevents the map scene from being offloaded after the player opens a menu or triggers a battle. It is an alternate solution to remove the lag after closing the menu and back into the map. You can also use a cache plugin for a substitution. This plugin is just straight forward and prevents the reloading of the map, until you go to another map or back to the title screen.

You probably don't need it if your maps are lite. But if you have already experienced lags, you can try it.

How to use:
It is plug-and-play.  Just install it and enable it in the plugin manager.

Change to gameplay
None. Except maybe if you create custom sprites in the map scene using script, open and close the menu won't remove them because the map scene is kept unchanged

Term of use:
You can use it in any project, credit is not required but appreciated.
