Fixed issue in USBtoSerial demos where the USART Rx line was not having its pullup enabled at startup, leading to noise being received from the Rx pin when left floating.

Removed unused relative Common.h header include from the DriverStubs board stub drivers.

Fixed Benito programmer, use the correct LED functions where needed to ensure correct status display at all times.

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.

Rename TOTAL_NUM_CONFIGURATIONS to FIXED_NUM_CONFIGURATIONS, to match the existing FIXED_CONTROL_ENDPOINT_SIZE compile time option. Add FIXED_NUM_CONFIGURATIONS to the descriptors of each project using the option.

Change project makefiles so that the current target settings and not just the board selection is printed during the build process.

Fix warning in AudioOutput demos when AUDIO_OUT_STEREO output mode is selected.

Changed AudioOutput demos to explicitly use timer 3 - the smaller USB AVRs where timer 1 was needed instead did not have the endpoint size neccesary for good audio throughput anyway.

Fix Benito documentation indicating erronously that the project used the HID USB class instead of the CDC class.

State information for class drivers is now zeroed out during enumeration (both in device and host mode) to ensure sane values after each enumeration. User code should no longer explicitly set state information as this is no longer preserved.

Ensure new Benito Programmer project matches Don's established LED behaviour - flash LED while generating target /RESET pulse, ping-pong LEDs during enumeration.

Added new Benito project, a simple modified USB-to-Serial bridge for the programming of AVRs using the official Arduino bootloader.
