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.

Oops - need to turn off USART via control register B before reconfiguring, fix ordering of USART control register modifications in the Benito and USBtoSerial projects.

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.

Minor update to the LowLevel MassStorage device demo, so that the ReadInCommandBlock() performs the data OUT endpoint selection and packet arrival test.

Move over message ID specific header data to unions inside the standard TMC header structure, so that all header data is read in one chunk in the incomplete TMC demo.

Rename reserved members of all structs so that they are uniformly named across all demos/projects/bootloaders.

Added start of the Incomplete TMC demo's command parser code.

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.

Convert over internal pseudo-function macros to true inline functions for added type-safety and compile-checking.

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.

Oops - ACL layer Bluetooth_SendPacket() function should check and allow NULL channels, since that indicates a control channel request.

Fix up Doxgen documentation for the Bluetooth stack code.

Rename Bluetooth stack function parameters to clearly indicate what sort of Bluetooth channel (ACL, RFCOMM) is required for each parameter, to make the code easier to read.

Add a new RFCOMM_ChannelSignalsReceived() Bluetooth stack callback from the RFCOMM layer for when the remote device sends new terminal control signals.

Fix RFCOMM_SendData() not aborting correctly when the requested RFCOMM channel is not found.

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().

Add a new RFCOMM_ChannelOpened() callback event for when logical RFCOMM channels are opened in the BluetoothHost demo. Make the demo echo back sent characters to the remote device.

Move out Bluetooth stack callback functions to a seperate BluetoothEvents.c/.h set of files for clarity in the Incomplete BluetoothHost demo. Add a new stack callback for opened ACL channels, make the demo save the RFCOMM channel when opened so that it does not have to search for it on each iteration of the main program loop.

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.
