Fixed CDC and RNDIS host demos and class drivers - bidirectional endpoints should use two seperate pipes, not one half-duplex pipe.

Minor code cleanups, remove TemperatureDataLogger host application's Visual Studio Solution files, add LibHIDNet license files.

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.

Fixed DFU bootloader programming not discarding the correct number of filler bytes from the host when non-aligned programming ranges are specified (thanks to Thomas Bleeker).

Enhance TemperatureDatalogger project -- add RTC capabilities so that data is logged along with the current time and date. Make logging interval configurable, set by a C# PC host application.

Fix up the incomplete Webserver project so that it integrates with the uIP stack correctly. Add simple HTTP webserver as a placeholder until FatFS can be integrated.

Begin to look into the RNDIS Host Class Driver, which seems to crash on test hardware after many packets have been received.

Update library manual with the new XPLAINBridge project's dual mode bridge/programmer functionality.

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.

Clean up and add more comments to the AVRISP-MKII project. Make sure the SPI_MULTI command handler supports multiple packet responses. Use slightly smaller/faster repeated indirect-load commands when retrieving the PDI target's memory CRCs.

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.

Fixed incorrect interface values in the VirtualSerialMouse and KeyboardMouse demo class driver structures.

Added caveat information to the CDC device class driver.

Added support to the MIDI Class drivers for packed data, where multiple MIDI events are packed into a single USB packet. Added new MIDI Class driver flush routines to override packing behaviour.

Inline USB management functions in the Class drivers which are standardized but currently unused, to prevent them from using up unneccesary cycles and flash in the user application.

Fix MassStorageKeyboard demo USE_INTERNAL_SERIAL check being performed before the required library headers were included, causing a compilation error.

Added notes to the class driver functions indicating which functions require what Device/Host state machine states to function.

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

Reduced guard bit time in the AVRISP project PDI/TPI protocols to reduce the time needed to reverse the data communication direction.

Fixed AVRISP PDI race condition where the guard time between direction changes could be interpreted as a start bit. Fixed TPI interface lines not being changed correctly when in bit-banged TPI mode.

Change the AVRISP project's RESET LINE makefile tokens to AUX LINE, as it is not always used for target reset.

Fix TPI NVM Write handler -- AVRStudio sends out writes in page sized chunks, not byte sized chunks.
