Add special support to the AVRISP-MKII for the new model USBTINY-MKII's additional LED to indicate target power source.

Add support to the USBTINY-MKII's additional LED in the board's LED driver header.

Changed LED indicator masks for the AVRISP-MKII project, so that there are defined roles for each LED.

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.

Use static inline intermediatary functions in Endpoint.h to handle the masking for the private endpoint configuration routine, instead of performing the masking in the Endpoint_ConfigureEndpoint() macro.

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.

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

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

Move and rename DevChaper9.c/.h and HostChapter9.c/.h to the HighLevel directory, new named DeviceStandardReq.c/.h and HostStandardReq.c/.h.

Rename LowLevel.c/.h to USBController.c/.h.

Remove dependancies on the complete <avr/io.h> header in the HighLevel USB driver directory, to ensure less work is required in later (possible) ports.

Reduce spacing of the structure elements in StdDescriptors.h to make the code more readable.

Fixed MIDI_Device_SendEventPacket() not correctly waiting for the endpoint to become ready (thanks to Robin Green).

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.

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.

Fixed HID device class driver still using PrevReportINBuffer for GetReport control requests even when it has been set to NULL by the user application (thanks to Axel Rohde).

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.

Minor tweaks to the library documentation.

Spell check code and manual pages. Remove custom Doxygen CSS stylesheet, as the new 1.7 Doxygen's default stylesheet is much better.

Fix HID parser documentation for the default maximum report/path/etc. elements so that it matches the current code values.

Speed up calls to Pipe_IsPipeBound() by immediately skipping unconfigured pipes, rather than performing token check first.

Better fix to avoid void pointer arithmetic in ConfigDescriptor.h to regain C++ compatibility (thanks to Michael Hennebry).

Remove void* arithmetic in the USB_GetNextDescriptor() static inline function, to make the header file C++ compatible once again. Implement workaround for an obscure GCC bug which can cause incorrect code generation under some circumstances when the void* is re-cast.

Small tweaks to ConfigDescriptor.c/.h to ensure pointers use the correct type, and to remove const attribute from the descriptor comparator callback function pointer type define, and into the function prototype instead.

The EEPROM stream read/write functions now use eeprom_update_byte() instead of eeprom_write_byte(), so that only changed bytes are written to EEPROM to preserve its lifespan.

Changed over the AVRISP-MKII and TemperatureDataLogger projects to use eeprom_update_byte() when writing non-volatile parameters to EEPROM to preserve its lifespan.

Remove incorrect check for the current device state in the Set Configuration request handler of DevChapter9, which broke Set Configuration requests to the device under most circumstances.

Move out the SPI prescaler list to a PROGMEM module-level variable in ISPTarget.c.

Fixed possible device lockup when INTERRUPT_CONTROL_ENDPOINT is enabled and the control endpoint is not properly selected when the ISR completes.
