0.85.0 New Feature - Reads Hobby Boards UVI sensor (UVI2-R1-A)

Oww records the UVI (UV index) value logged by the sensor.
This is drawn as a coloured box on the Oww main window,
according to the WHO standard colouring. The index is written
to the auxillary window.

UVI values are transmitted through the owwl protocol.

UVI values my be written to your logs using the new parser entry:
    
    $uvi1$
    
Of course if you have more than one sensor you can enter a different
number.

The sensor is factory-set to adjust readings to allow for the loss
through the window of the Hobby Boards box. Oww ignores the
"in case" flag, so if you are not using a window (somewhere it never 
rains?) you should enter calibration values to adjust the scaling
to allow for this.

WSI603 T readings:
    
I found the AAG WSI603 was giving some bad T readings. Oww now uses
an undocumented feature of the bit pattern read for DS2760 temperatures
to spot these.
