Added sulfur chemistry to dictionary.txt, tree.txt, and rateLibrary.txt in
Birad_recombination.
Merged databases for Disproportionation.

Added Aaron Vandeputte's sulfur input to dictionary.txt, tree.txt, and
rateLibrary.txt in Disproportionation.
Merged databases for Intra_R_Add_Endocyclic.

Added sulfur to library.txt and tree.txt in Intra_R_Add_Endocyclic.
Added sulfur to intra_H_migration.

Modified dictionary, rateLibrary and tree in intra_H_migration.
Added sulfur to R_Recombination.
