Eliminate duplicate group in Intra_RH_Add_Exocyclic family.
Update R_Addition_CSm family to reflect changes due singlet restriction on CS.

See commit 8c656a9c1c5798 for details on similar changes to R_Addition_COm

Updated reaction recipe so that we are changing lone pairs rather than radicals.
Change default usage of R_Addition_CSm family to 'False'.

This was done on a recommendation by @cclass86
Revert most intermediate adjlists in kinetic groups to old style format.

Turns out only R_Addition_COm had almost all the intermediate adjlist style groups.
To keep consistent with the other family I reverted them back.
