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.

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.

Add missing TWI_Init() call to the TemperatureDataLogger project. Make DUMMY_RTC compile time option the default, so that it works correctly on the USBKEY and other Atmel boards out of the box.

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.
