More spell checking of all source files -- correct missed errors, switch to EN-GB spelling dictionary.

Fix typo in DualVirtualSerial.c due to the changed CDC Device APIs that was preventing the demo from being compiled.

Altered the CDC Deivice and Host Class drivers' receive byte routines, so that no data is indicated by a negative return value.

Added auto flushing of OUT data to the CDC Host Class driver's USBTask function to automatically flush the send pipe buffer.

Added support to the AVRISP-MKII project for ISP speeds slower than 125KHz via a new software SPI driver.

Added new SPI_ORDER_* data order masks to the SPI peripheral driver.

Add missing INTERRUPT_CONTROL_ENDPOINT compile time option to the Mass Storage device projects/demos and incomplete Test and Measurement Class demo, which was accidentally removed during the makefile updates.

Alter Test and Measurement Class demo's request handlers to accept, process and correctly return the fields indicated in the specification.

Add stream callback flags and class specific control request handler code to the incomplete Test and Measurement Class device demo.

Change over the keyboard demo's manufacturer name back to the primary author of the demo.

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

Add missing const qualifiers to the demos.

Indent core library function parameters so that there is only one parameter per line, to increase readability.

Add new module source variables to the library core makefile, so that module sources can be added to a project's makefile on a per-module rather than per-file basis.

Disable strict aliasing explicitly in the project makefiles, as this is apparently enabled by default in newer AVR-GCC builds, and aliasing is used heavily for type-punning through the LUFA and third party library's codebase.

Removed the automated checking of event names in the demo, project and bootloader makefiles due to inconsistancies between the behaviour of the command line tools used to perform the check on each platform.

Removed the internal endpoint and pipe memory allocation macros, as this is already performed directly in the code. Simplify the endpoint and pipe reset procedure.

Rewrote the implementation of the SwapEndian_16() and SwapEndian_32() functions so that they compile down in most instances to minimal loads and stores rather than complicated shifts.

Fixed SCSI.c implementations of all the demos/projects casting the block count to a 32-bit temporary before calling SwapEndian_16().

Added new Drivers/USB/LowLevel/Device.c file to house Device mode specific functions that are more complicated than simple macros. Moved USB_Device_SendRemoteWakeup() to the new Device.c source file and corrected it to unfreeze and restart the USB controller clock before issuing a Remote Wakeup request.

Removed the USB_Device_IsRemoteWakeupSent() and USB_Device_IsUSBSuspended() macros, as they are now obsolete.

Fix Doxygen formatting of parameters for the CALLBACK_HID_Device_CreateHIDReport() function in the ClassDriver HID device demos.

Minor fixes to demos to add in some missing comments, printf() formatting. Make incomplete Bluetooth demo indicate connections visually via the board LEDs.

Fixed RNDISEthernet demos crashing when calculating checksums for Ethernet/TCP packets of more than ~500 bytes due to an overflow in the checksum calculation loop (thanks to Kevin Malec).

Removed string Attributes from the Service Discovery Protocol code to minimise the potential points of failure while the base code is being debugged.

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

Add new ReportType parameter to the HID class driver device callback and host report sending routines.

Renamed internal Host mode Class driver descriptor comparator callback routines so that they all start with a uniform DCOMP_{Class Abbreviation}_ prefix.

Add svn:eol-style property to source files, so that the line endings are correctly converted to the target system's native end of line style.

Change over instances of "make" in the makefiles to "$(MAKE)" to allow for the make tool to be overridden.

Remove incorrect Abstract Call Management class specific descriptor from the CDC demos, bootloaders and projects.

Relocate USBInterrupt.c/.h from the HighLevel USB driver directory to the LowLevel directory as it is hardware-dependent.

USB_Init() no longer calls sei() to enable global interrupts - this must now be done in the user application once all init code has run.

Minor documentation improvements.
