Started implementing the low level PDI protocol in the AVRISP project, for XMEGA device programming.

Updated Benito project -- added hardware interrupt and software buffering for serial data reception to prevent missed characters, condensed pulse generation counters into a struct for clarity.

Added check to CDC_Device_BytesReceived() to ensure 0 is returned when device is not enumerated to a host.

Move AVRISP project's V2Protocol_DelayMS() function to be static inline, as it is now very minimal. Added extra project doxygen documentation.

Fix to V2 Protocol for Fuse/Sig/Lock byte read -- off by one error on the array when writing back the response from the device.

FLASH/EEPROM reading and writing currently broken and unfinished, respectively.

Added documentation of the makefile CDEFS values to the MagStripe project.

Move AVRISP Programmer project to a new Unfinished subdirectory of Project while it is under development.

Added new Endpoint_SetEndpointDirection() macro to set the current endpoint direction for bidirectional endpoints.

Renamed internal USB_INT_ENDPOINT_SETUP macro to USB_INT_RXSTPI to fit in with the rest of the interrupt vector macros.

Renamed all library events to properly seperate out Device and Host mode events. Changed the firing conditions for some events to ensure that events are fired by their own USB mode only.

Remove VBUS events - not needed as the library takes care of VBUS detection and feedback on supported AVRs via the USB_Device_Connected and USB_Device_Disconnected events.

Fixed incorrect Host state assignment in the incomplete BluetoothHost demo.

Fixed incorrect ENDPOINT_EPNUM_MASK mask preventing endpoints above EP3 from being selected (thanks to Jonathan Oakley).

Removed STREAM_CALLBACK() macro - callbacks now use regular function definitions to clarify user code.

Removed DESCRIPTOR_COMPARATOR() macro - comparators should now use regular function definitions to clarify user code.

Corrections to Keyboard demo.

Removed AVRISP_Programmer project due to code quality concerns.
