Add logical grouping of related #define values for better Doxygen documentation.

Changed over www.fourwalledcubicle.com links to the new www.lufa-lib.org redirect domain, including the new aliased links for LUFA-related pages such as the various download/source control mirrors and support lists.

Added new NO_CLASS_DRIVER_AUTOFLUSH compile time option to disable automatic flushing of interfaces when the USB management tasks for each driver is called.

The MIDI class drivers now automatically flushes the MIDI interface when the MIDI class driver's USBTask() function is called.

Changed AudioInput and AudioOutput demos to reload the next sample via an interrupt rather than polling the sample timer.

Add descriptor class, subclass and protocol constants to the class drivers, modify all demos to use them where possible.

Move out private/internal host class driver constants to the common class driver headers, so that they can be used in the Low Level host mode demos.

Ensure all demos, projects and bootloaders use the class driver constants where possible to minimise code repetition.

All USB class drivers are now automatically included when LUFA/Drivers/USB.h is included, and no longer need to be seperately included.

All LowLevel demos changed to use the constants and types defined in the USB class drivers.

Better algorithm to extract and convert the internal device serial number into a string descriptor (if present).

Fix incorrect warning text when an unsuitable F_CLOCK value is given.

Add missing  ENDPOINT_ATTR_NO_SYNC and ENDPOINT_USAGE_DATA attributes to the descriptors in the ClassDriver MassStorageKeyboard demo.

Renamed ENDPOINT_DOUBLEBANK_SUPPORTED() to ENDPOINT_BANKS_SUPPORTED() and changed it to return the maximum number of supported banks for the given endpoint.

Fix incomplete StandaloneProgrammer project code not compiling due to the recent API changes in the LUFA core.

Fix SoftUART.c not compiling due to accidental check in of changes not yet complete in the rest of the XPLAINBridge project code.

Fixed MIDI_Host_Flush() not aborting early when the specified MIDI host interface was not configured.

Small documentation improvements to explicitly reference tokens in Doxygen, to ensure that they are converted to cross-reference links in the output files.

Fix Webserver project code not compiling due to the changes to the USB mode selection constant names.

Moved the USB device selection logic for ENDPOINT_TOTAL_ENDPOINTS further up in Endpoint.h to where the endpoint bank capabilities are determined, to reduce the total number of device-specific logic.

Change USB_Host_WaitMS() to test and disable the HSOFI interrupt before resuming the bus, so that it does not fire before the delay loop has run.

Add missing const qualifier to the parameter of USB_Host_ClearPipeStall().

Fixed random enumeration failure while in device mode due to interrupts causing the Set Address request to exceed maximum timings.

Remove MIDI ClassDriver device demo's accidental inclusion of the unused ADC peripheral driver header file.

Fixed ISR definition conflict in the XPLAIN bridge between the software UART and the AVRISP-MKII ISP modules.

Added new NO_SOF_EVENTS compile time option, enabled in the bootloaders to reduce the compiled binary size.

Added SVN eol-style property to the library driver files that are missing it.

Cache the USB_DeviceState variable internally in the library core when multiple checks are required in a single loop iteration, to reduce compiled code size.

Revert change to the AVRISP-MKII project for fuse byte programming via the CMDEX bit - this appears to be an error in the XMEGA manual external memory programming table.

Fixed broken FLASH/EEPROM programming in the AVRISP-MKII clone project when writing in non-paged mode and the polling byte cannot be used.

Fixed LowLevel JoystickHostWithParser demo not saving the chosen HID interface's report descriptor size.

Simplified low level Host demo configuration descriptor parser routines.

Make Printer Host mode Class driver interface descriptor search routine pre-cast the current interface descriptor to simplify the value checks.

Make Host mode Class drivers only set the class driver instance's state values once a compatible interface has been found within the device.
