[CGMZ] Rumble - Version Alpha R3

Hi all, today this plugin was updated to version AlphaR3!
This update adds automatic rumble during certain key events. These include: shop buy/sell, battle trigger, and damage taken or dealt. You do not have to use these, as by setting the rumble to a duration of 0, these rumbles will not take place when these actions occur.
Let me know your suggestions if you would like automatic rumbles at other points in the game.
