Subsurface ignores a temp of 0˚C

[Henrik Brautaset Aronsen]

It looks like Subsurface believes that 0˚C == no temperature sample.

If you look at macdive-data.png, the dive starts at 0˚C, goes down to 
-1˚C, and goes up to 2˚C and beyond.

The same dive in subsurface-data.png:  No samples before -1˚C at 2:30 
min, and that seems to be interpreted as air temp.

And last but not least, subsurface-graph.png: The graph starts at about 
2˚C at 5:00 min.  Where are my manly degrees below zero? :)
