gSales Plugin Update auf v1.6.2

A longer known error concerning the transmission of fields with special characters has been fixed. The background is that gSales did not accept special characters (UTF8) for a long time and the gSales plugin had edited the contents. Meanwhile gSales provides speical characters encoding so it was double encoded, which led to this error.
