Planner: Unify final ascent rates in plan() and fake_dc()
When generating fake profiles for manually entered dives, fake_dc() and plan() used different final ascent rates of 5 m/min and 4.5 m/min, respectively. This led to dives that were 6 seconds longer than entered by the user and to confusion. See #554. Therefore, use the same ascent rate taken from the preferences field flag.ascratelast6m in both cases. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
