Fixed USB_CurrentMode not being reset to USB_MODE_NONE when the USB interface is shut down and both Host and Device modes can be used (thanks to Daniel Levy).

Add new manual pages detailing the advantages of LUFA over the official Atmel USB AVR stack, and reasons why LUFA should be used over a built-from-scratch USB stack.

Removed interrupt disable/enable from the Device mode control request processing routines, as they can cause problems with user code and can cause infinite spinlocks under some circumstances.

Added new LUFA logo from EDIGMA.COM.

Redocumented all device demos, now that they have changed over to the new USB class drivers.

Added C linkage to class drivers for C++ support.

Added prefixes to most of the class driver constants to prevent name clashes.

USB_IsConnected is now cleared before the USB_Disconnect() event is fired in response to VBUS being removed.

Minor documentation improvements.

Fixed bug in RNDISEthernet and DualCDC demos not using the correct USB_ControlRequest structure for control request data.

Fixed documentation showing incorrect USB mode support on the supported AVRs list.

Changed HWB board driver to Buttons driver, to allow for the support of future boards with more than one mounted GPIO button.
