Corrected incorrect signature bytes for the AT90USB82 and added support for the ATMEGAXX2 variant AVRs to the DFU bootloader.
Added warning to the EVENT_USB_Device_Connect() and EVENT_USB_Device_Disconnect() events that they may be fired multiple times during device enumeration on the series 2 AVRs.
