Implementation of FC's improved Newtonian configuration: more realistic (and tunable) friction & fields towards which to relax and planet parameters (gravity, radius, rotation rate...) can be read in from a planet.def file (this occurs only when running in "newtonian mode"; planet parameters are otherwise read in from the start file).
Checked that these implementation don't change results when running standard Earth bench tests on Vargas.
