Fix SoftUART.c not compiling due to accidental check in of changes not yet complete in the rest of the XPLAINBridge project code.

Fix incorrect ADC driver documentation for the parameters of ADC_Init(), fix incorrect call to ADC_Init() in the TemperatureDatalogger project.

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

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.

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.

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.

Removed two-step endpoint/pipe bank clear and switch sequence for smaller, faster endpoint/pipe code.

Added spacing between multiple paragraphs in Doxygen \note sections.

Removed call to the clock prescaler reset function in the Teensy bootloader to save space - the user application is accessed via a watchdog reset anyway, so the prescale reset would only affect the speed of the bootloader itself.

Remove accidentally duplicated model-specific peripheral driver files.

Fixed ADC routines failing to read the extended channels (Channels 8 to 13, Internal Temperature Sensor) on the U4 series USB AVR parts.

Added a timeout value to the TWI_StartTransmission() function, within which the addressed device must respond.

Fixed TWI_StartTransmission() corrupting the contents of the GPIOR0 register.

Make SPI and USART peripheral dispatch driver headers in preparation for a set of AVR32 peripheral drivers.

Add more include protection macros to give the user warnings when they try to manually include private driver header files, instead of the public driver headers.

Fixed incorrect values of USB_CONFIG_ATTR_SELFPOWERED and USB_CONFIG_ATTR_REMOTEWAKEUP tokens (thanks to Claus Christensen).

Mark the AVRISP-MKII project descriptors as being both Bus Powered and Device Powered.

Copy over file level documentation of the peripheral drivers to the module level documentation.

Clean up Webserver project - add more Doxygen documentation for the new DHCP client functions and defines.

Fix TemperatureDataLogger and Webserver project builds.

Added explicit ADC channel masks for the standard set of ADC channels, as the single-ended channel MUX masks are not equal to the channel number on some AVR models. Changed demos to use the new channel masks when using the ADC driver.

Changed XPLAINBridge project to be both a USB to USART bridge and a PDI programmer, based on the state of a mode select pin.

Fixed a bug in the incomplete Webserver project, where the packet data was not being written to and read from the correct buffer address.

Fixed lack of support for the ATMEGA32U2 in the DFU and CDC class bootloaders

Changed incomplete Webserver project over to using the uIP timer library.

Add new TemperatureDataLogger project, a simple USB Mass Storage class Temperature Data Logger using the onboard Dataflash and Temperature sensor.
