Adding basic mouse button support - Full Mouse support will have to wait for KLL 0.6 * This will include dynamic HID descriptor generation for many wheels and axis depending on the KLL needs - HID descriptor is currently limited to 8 buttons - Technically mouse movement also works (tested by accident), but it's disable for now (needs some API thought) - Adding additional udev rules - Added KRO mode default define
