The old code was wild: For the yearly statistics it would allocate one entry per dive in the log. Of course, it would also leak C-style strings. Convert the whole thing to somewhat idiomatic C++. Somewhat wasted work, because I'd like to convert the whole thing to the new statistics code. But let's finish the conversion to C++ first.
