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.

Add first draft of the TPI NVM commands for reading, writing and erasing a target. Needs testing when physical access to a part is available.

Add dummy undocumented TPI XPROG parameters to the AVRISP project so that TPI programming mode can be entered.

Fix mistakes in the XPROGTarget.c/.h files for TPI mode software USART clock rate and PDI mode XPLAIN board autoconfiguration.

Remove missed timer 0 init code in the ISP protocol handler in the AVRISP project. Switch the XPROG protocol target communications handler over to using Timer 1 COMA/COMB ISRs for the two physical layers, rather than COMA/ICR1. Speed up bit-banged USART mode slightly.

Added command timeout to the AVRISP project so that incorrectly connected targets no longer freeze the device.

Removed string descriptors from the TeensyHID bootloader to reduce its size.

Complete combining of PDI and TPI target communication code files, stub out TINY NVM controller functions.

Rename PDITarget.c/.h to XPROGTarget.c/.h so that both PDI and TPI programming can be included in the one set of files.

Combine AVRISP project TPI and PDI lib directories - these protocols use the same underlying XPROG wrapper for the host-to-programmer command wrapping.

Correct include paths and makefile for the AVRISP project now that the protocol handlers are in seperate directories.

Make seperate ISP, PDI and TPI folders in the AVRISP project Lib subdirectory to hold each protocol's files.

Lower timeout periods in the AVRISP project. Increment firmware minor revision number in the AVRISP project so that it remains comatible with the latest AVRStudio without an upgrade warning.

Fix TeensyHID bootloader - change vendor page in the descriptors to match the undocumented page needed for the new Teensy 2.0 boards.

Commit for the 091223 release.

Correct TeensyHID bootloader descriptors to use the correct revision code for the ATMEGA32U4 based Teensy revision.
