Slightly speed up software USART in the AVRISP project - faster parity computation, ensure received data is byte aligned when receive is complete by throwing away the start bit during reception.

Use the PDI REPEAT instruction in the PDI programmer code to reduce protocol overhead and greatly improve transfer throughput. Switch bit-bang USART in the AVRISP project to Timer 1, so that Timer 0 can be used for hardware timeouts while waiting for the NVM bus or controller to become ready.

Split out NVM access code in the AVRISP project into a seperate NVMTarget.c source file and header. Make NVM register accesses use the NVM base address as set by the host, rather than using the fixed value from the XMEGA datasheet.

The AVRISP project can now enter PDI mode under both bit-bang and hardware USART connection modes, tested against the XPLAIN board hardware. Still need to complete higher level NVM access code so that the device's memories can be read and written.

Change over AVRISP project to have both hardware USART and software USART modes for the PDI protocol, when enabled. Fix up PDI initialisation routines.

Fix inverted bit-banged USART logic in the AVRISP project for PDI programming. Add a delay to the clock toggling in the AVRISP project to ensure that the programming speed does not exceed 10MHz under any conditions to satisfy the limits in the datasheet for all target voltages. Fix incorrect pin being used as the DATA in in PDI programming mode.

Fixed HID Parser not distributing the Usage Min and Usage Max values across an array of report items.
...
Added new HID_ALIGN_DATA() macro to return the pre-retrieved value of a HID report item, left-aligned to a given datatype.
Added new PreviousValue to the HID Report Parser report item structure, for easy monitoring of previous report item values.

Document the PDI programming routines implemented so far in the AVRISP project. Add ability to selectively disable ISP programming support in addition to the existing ability to disable PDI programming support.
