Restricted Creative 1.4

-I added a couple of features to allow for support of plugins that change your game mode for you when you enter a region. This will stop players from opening an inventory (not their own) when they are outside of the region / whatever feature changes game mode, and checks when their game mode changes that their top inventory is their own inventory, not anything else.

-Also added a backup safety feature for the inventory click event which also checks for the player's top inventory > cancels > closes

-Added a couple of full stops on permission messages so that messages are consistent and *hopefully* professional looking.
