Fix Dataflash driver for the A3BU-Xplained board.

Minor documentation improvements.

Fix errors in the new Micropendous board drivers. Reorder the board definition macro indexes so that misspelled board names default to BOARD_USER rather then BOARD_USBKEY.

Added new LEDs_Disable(), Buttons_Disable() and Joystick_Disable() functions to the board hardware drivers.

Run wspurify script on /trunk/ and /branches/ C source files, to remove any trailing whitespace at the end of each line.

More XMEGA USB core fixes.

Fix duplicated LED driver functions in the Doxygen documentation.

Slight improvements to the ADC peripheral driver example in the manual.

Fix inverted LEDs_GetLEDs() result for the EVK1100 and EVK1101 boards.

Massive corrections to the project documentation and code comments, thanks to Russian translation services provided by Andrey from Microsin.ru.

Replace all calls and references to _delay_ms() in the code with the architecture-agnostic Delay_MS() function.

Improve code generation for the Delay_MS() function on the AVR8 architecture when called with a constant input.

Add new ARCH option to the makefiles to (eventually) specify the target device architecture. Update non-usb peripheral drivers to reflect future multiple architecture support.

Documentation improvements - put driver example code into its own section, fix incorrect and missing section names.

Made the USARTStream global public and documented in the SerialStream module, allowing for the serial USART stream to be accessed via its handle rather than via the implicit stdout and stdin streams.

Fixed calculation of timer register reload values derived from F_CPU; must subtract one from the division result for the compare value to be correct.

Change AVRISP-MKII rescue clock speed to 4MHz to ensure that a 125KHz ISP speed works regardless of the target's fuses (i.e. DIV8 set).

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