Add working device: RDing TEMPer1V1.4 0C45:7401

I've compiled the code and tested it with my new usb thermometer (as above) and it is working with the current code:

~/Development/usb-thermometer/TEMPered/build/utils$ sudo ./tempered
/dev/hidraw2 0: temperature 21.88 °C

dmesg output:
[11274.289928] usb 2-1.1: new low-speed USB device number 6 using ehci_hcd

I'm not sure whether the other hidraw device is relevant or just a different way of access the data; I'll do some more reading of the code and various docs here.

For reference, this is the device: http://www.ebay.co.uk/itm/PC-Laptop-USB-Powered-Thermometer-Temperature-Sensor-Data-Recorder-Mini-489-UK-/290913820488?pt=UK_BOI_Electrical_Test_Measurement_Equipment_ET&hash=item43bbd09f48

Thanks for the code :)
