"KCS" v3.9.1 firmware BIN file download

Another update, there are two different types of DHT22 sensors, the raw sensor with 4-pin connectors and a DHT22 module with 3-pin connectors and built-in pullup resistor.  I've just tested the second form and that also works now, with either a 5V or 3V feed.  In fact it works a lot better than the 4-pin DHT22, it's reported almost immediately by the board rather than only after several minutes, and it updates continuously rather than being frozen.
