New release of the firmware version 0.27

This release fixes bugs with the speed display when not logging speed.
This release adds support for 1-Wire DS18B20 temperature sensors.

New release of the firmware version 0.26.
This fixes bugs with the old version not logging properly. It also adds some optimisations in the makefile and main.h to allow for a smaller build

The website is now hosted at www.brokentoaster.com/butterflylogger but you should be automatically redirecte from the butterfly.sf.net site.

Some more documentation can be found at http://www.circuitcellar.com/avr2006/winners/DE/AT3221.htm

This will be incorporated into the project at a later stage.
