Limited support for Suunto DM4

[Amit Chaudhuri]

Ah.  I didn't spot the callback mechanism.  That explains why you implied
it worked and I was thinking "how?" In the few seconds I spent on it I was
looking for the sqlite3_step() calls to work your way through the result
set.

I might start by looking at my DM4 outputs and seeing if there are alarms
etc. that are not currently handled.
