with wetter soils (75% of saturated water content, as opposed to 15% of
absolute water content) for all FATES configurations. The rationale for
this is that in FATES-nocomp simulations, Jessica Needham was finding very
high initial mortality rates in some seasonal tropical forest regions which
she traced it back to the initial soil moisture killing off plants before the
ecosystem could get established.

This also updates the fates externals pointer to the latest tag which includes
a number of science updates since the last tag update and updates the the
default parameter file.
