Parcels v3.1.3: a Lagrangian Ocean Analysis tool for the petascale age

This is a minor update from Parcels v3.1.2, with one very important change: It fixes a bug in the polyTEOS10-bsq kernel, discovered and patched by @michaeldenes in #2133. See also our blog post that describes the impact of this bug.

Apart, from that, this PR features mostly very minor changes to the documentation; as well as a fix to the partition_function (#1953) by @JamiePringle.
