- added support for older versions
- added null binding for left/right click
this means if you hold one mouse button and press the other the first one gets canceled until the new one is released. works for anything you bind to Attack/Destory + Use Item/Place Block (doesn't have to actually be a mouse button) just make sure you also check the Null Bind keybinds and set the keybinds to whatever you are using for the actions
- Moved Null Bind keybinds to Movement category for easier configuration
