[CGMZ] Hooks - Version Alpha R4

Hi all, today this plugin was updated to version AlphaR4!
For default RMMZ hooks, this update adds a hook for game variable and game switch changes. Now you can run custom JS whenever you change a variable or switch.
For CGMZ hooks, this update adds hooks for dungeon tool use and interact. Now you can run custom JS whenever a dungeon tool is used, and whenever a dungeon tool interacts with an event.
This update also fixed a bug with the Skill Purchase hook for [CGMZ] Skill Shop, so the actor argument should now correctly populate.
- Added hook for variable change
- Added hook for switch change
- Added hook for dungeon tool use
- Added hook for dungeon tool interact
- Bug fix for skill purchase hook not providing actor
