Added class SinglePvtDead, add parameter 'props_use_spline' to simulators.

Recall that the class that used to be called SinglePvtDead has
been renamed to SinglePvtDeadSpline. If 'props_use_spline' is true,
that class is used (this is the default), which makes a monotone
spline that is uniformly, densely sampled. The new class simply
uses linear interpolation in the input tables.
