1. Make the domains of EmuWiimote & RealWiimote clearly separated, so I won't get tons of "Negative" and complaints about RealWiimote when I'm committing updates for EmuWiimote that has nothing to do with RealWiimote. 

2. Change the frequency of WiiMote report sending to 100Hz which complies with real Wiimote hardware.
