Make sure that LUFAConfig.h is included *after* the common submodules, so that the architecture and other defines are available to the configuration header.

Ensure the DFU bootloader disables and clears the activity LED toggle timer when a soft-reset to application space is used.

Merge in AppConfigHeaders branch to trunk, altering all projects and demos to use configuration headers for application and LUFA compile time settings, rather than defines in the project makefiles.

Oops - shell variables can't use the += operator - must reference the existing value in the new value to append.

Remove legacy AS4 project files, now that they can be automatically generated by the new maintenance script.

Add missing documentation to custom BuiltTest hardware mapping files. Fix up old copyright years on some makefiles.

Fixed swapped Little Endian/Big Endian endpoint and pipe write code for the UC3 devices (thanks to Andrew Chu).

Fix incorrect definition for the XMEGA Endpoint_BytesInEndpoint() function when used on OUT endpoints.

Oops - mask out the endpoint address direction when comparing the IN and OUT endpoint indexes in the AVRISP-MKII clone and XPLAINBridge projects.

Fix AVRISP-MKII clone and XPLAINBridge projects not properly configuring the AVRISP IN endpoint when needed if RESET_TOGGLES_LIBUSB_COMPAT compile time option is used.

Turn off watchdog before jumping to the user application in the DFU and CDC based bootloaders, for the specific case of /HWB being low during reset (where the bootloader will re-enter).

Alter the XPLAINBridge and AVRISP-MKII clone projects so that the descriptors from the AVRISP-MKII clone project can be directly used in the XPLAINBridge project. Add support for RESET_TOGGLES_LIBUSB_COMPAT option in the XPLAINBridge project.

Added new RESET_TOGGLES_LIBUSB_COMPAT compile time option to the AVRISP-MKII clone programmer project (thanks to Robert Spitzenpfeil).

Additional fixes to the MIDI host driver due to not unfreezing/re-freezing pipes correctly (thanks to Michael Brown).

Upgrade Doxygen configuration files for Doxygen 1.8.1, fix broken stylesheet and footer HTML, add explicit spacing into documentation code fragments to prevent Doxygen from removing empty lines in the output.

Minor documentation adjustments to the demos, projects and bootloaders to ensure correct formatting of application device support.

Update project Doxygen and makefiles so that the resulting project documentation hides the unused version value, and uses the same HTML CSS stylesheet as the library core.

AppConfigHeaders: Make sure that in applications using an AppConfig.h configuration file, all application headers include the configuration file.

AppConfigHeaders: Move out the last of the demo/app configurations into new AppConfig.h header files.

Clean up and speed up build tests by turning off expensive and slow size optimizations, and generation of assembly listings (*.lst) for each compiled source file.
