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
