Add user callback function to the Bluetooth host demo to filter out connections from remote devices. Add in ability to reject connections based on their bluetooth device address.

Clean up RelayBoard project code.

Make AVRISP project clear the XMEGA target's reset register twice; this does not appear to take affect properly the first time under some circumstances.
