Don't show surface events at the beginning or end of the dive

Browse source 
That's just annoying and pointless.  So we arbitrarily say that surface
events within the first and last 30s of the dive are suppressed.

But we now do show them in the middle, in case the sampling rate is too
low, and the profile itself doesn't show that we got to the surface.

These heuristics still needs tweaking - if the profile already shows
that we're at the surface, then we should probably suppress the event
triangle.

But in the meantime this at least gets rid of the truly pointless cases.
