Use new VERSION_BCD() macro with explicit int arguments to fix edge cases with the previous floating point macro version.

Add symbolic names for USB Device String Descriptors within the demos, applications and bootloaders.

AppConfigHeaders: Update several additional user projects to use configuration header files, rather than makefile defines. Remove compile time warnings for projects lacking device serial support, remove incomplete StandaloneProgrammer project.

Add branch for the conversion of demos to use standard C header files for configuration, rather than makefile defined macros.

Increased endpoint polling interval for all demos and projects to 5ms, as 1ms was causing some enumeration issues on some machines (thanks to Riku Salminen).

USB_CONFIG_ATTR_BUSPOWERED constant renamed to USB_CONFIG_ATTR_RESERVED, as this was misnamed (thanks to NXP Semiconductors).

Removed the ENDPOINT_DESCRIPTOR_DIR_* macros in favour of the shorter ENDPOINT_DIR_* macros, which can now be used with both Endpoint_ConfigureEndpoint() and in the device descriptors.

Add const to all project descriptor definitions for safety.

Added new HID_DESCRIPTOR_MOUSE, HID_DESCRIPTOR_KEYBOARD and HID_DESCRIPTOR_JOYSTICK macros for easy automatic creation of  basic USB HID device reports.

Abuse the the C preprocessor so that the HID macros can automatically encode data into the array from the HID macros automagically, by specifying the bit-width of the data, and the data itself as a single integer value of that width.

New HID report item macros (with HID_RI_ prefix) to allow for easy creation and editing of HID report descriptors.

Changed over all project and demo HID report descriptors to use the new HID report item macros.

Moved the HIDParser.c source file to the LUFA/Drivers/USB/Class/Common/ directory from the LUFA/Drivers/USB/Class/Host/.

Lower bulk endpoint polling rate in the descriptors to the lowest possible value to give maximum throughput.

Fixed incorrect PollingIntervalMS values in the demo/project/bootloader endpoint descriptors (thanks to MCS Electronics).

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.

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.

Reverted Endpoint/Pipe non-sequential configuration hack, placed restriction on the configuration order instead to ensure maximum reliability.

Altered all low level device and host mode demos to ensure that endpoints and pipes are configured in ascending order properly.

Rewrote all low level host mode demos' configuration descriptor parser code to ensure that pipes are enumerated in ascending order, and to ensure maximum compatibility with devices.

Incremented all device mode demo's device descriptor revision numbers to ensure that any descriptor changes are re-fetched on machines which have enumerated previous versions.

Add new CDC descriptor structs to the CDC class driver, so that the CDC demos can use human readable field names.

Rename prefix for Still Image Host class driver functions from "SImage_" to "SI_" to remain consistent with the rest of the driver.

Changed the signature of the CALLBACK_USB_GetDescriptor() callback function so that the descriptor pointer is const, to remove the need for extra casting inside the callback (thanks to Jonathan Kollasch).

Update all demos, projects and bootloaders to indent all function parameters, one per line, for better readability.

Add missing const qualifiers to the demos.

Renamed CDC device class demos' ManagementEndpoint descriptor to NotificationEndpoint to more accurately indicate its purpose.
