Rebase on 5.13.beta2
Trac #15288 : Theorem 7.20 is now a function of its own, plus some fixes
Trac #15705: PowerSeries.ogf() and .egf(): match name and definition to behaviour
First (slow but functional) implementation of reduced Kronecker product; also, t-completion of a partition (the docstring is probably more useful than the code here), and (unrelatedly) an additional option (and improved doc) in the partitions-to-Dyck-paths method.

trac #15287: merge with updated #15286
immaculate functions for arbitrary integer vectors
omega involution on NSym; alias for omega involution on Sym (to have notations match); subtle changes in duality pairing to avoid unadorned sum([...]).
omega involution on QSym
verschiebung on elementary basis of NSym
implemented internal product on Psi using NCSF2 Lemma 5.10; not using it as default because of its ugly worstcase running time
Merge branch 'public/combinat/sf/reduced-kronecker' of trac.sagemath.org:sage into nsym
