Force TTS/NDL calculation off if things take too long

This is kind of a random cut off, but if plotting the dive takes more than
a second and TTS/NDL is on, we force it off. Because the algorithm for
that is fundamentally quadratic in nature it can take a VERY long time -
getting users to think something is broken.
