Fixed device state not being reset back to the default state if the host sets the address to 0x00.

Fixed Set Configuration requests not being stalled until the host has set the device's address.

Fixed possibility of internal signature retrieval being corrupted if an interrupt occurs during a signature byte read (thanks to Andrei Krainev).

* Note that this design currently has the following limitations:
* - Minimum ISP target clock speed of 500KHz due to hardware SPI module prescaler limitations
* - No reversed/shorted target connector detection and notification
* - Very slow TPI and PDI programming when in software emulated USART mode
*
* On AVR models with an ADC converter, AVCC should be tied to 5V (e.g. VBUS) and the VTARGET_ADC_CHANNEL token should be
* set to an appropriate ADC channel number in the project makefile for VTARGET detection to operate correctly. On models
* without an ADC converter, VTARGET will report a fixed 5V level at all times.
*
* When compiled for the XPLAIN board target, this will automatically configure itself for the correct connections to the
* XPLAIN's XMEGA AVR, and will enable PDI/TPI only programming support (since ISP mode is not needed). Note that the
* first revision XPLAIN board lacks a bootloader on the AT90USB1287, and thus for this firmware to be loaded, an external

* While this application can be compiled for USB AVRs with as little as 8KB of FLASH, for full functionality 16KB or more
