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.
