Fixes to R_Addition_CSm using checkWellFormed

C atoms changed to Cs in CSm;CH2CH3 rule to match the CH2CH3 group
Fix errors in 1,2_Insertion found with databaseTester

-Moved a comment at the top to the longDesc of the nodes it affects. They
were originally referenced by index, but who knows when that might get
reshuffled/changed

-replaced C with Cs in all instances of 'carbene'

-Many groups had their *2 atom (therefore always in group2 for
group1;group2) changed from C to Cs or Cd to match the definition in
groups.py. Listed below is all the rules affected:
CO_birad;C_pri/NonDeC
carbene;C_pri/Ct
carbene;C_pri/Cd
carbene;Cd/H/OneDe
carbene;Cd_pri
carbene;C_pri/Ct
carbene;ethene (2 atoms changed from C to Cd)
CO_birad;C/H2/NonDeC
carbene;Cd/H/NonDeC
CO_birad;C_methane
Fixes to H-Abstraction family: Part 1

First of many changes to H-Abstraction family found by the databaseTester.

-Group definition (groups.py) of C/H/CtCt somehow got mixed up to: '1 *3
R!H 2'. Changed back to correct definition based on its rules and java's
definition

-"Cd_pri" was previously changed to include N. A child underneath it
"Cd/H2/NonDeC", is it's previous definition without N. 48 rules had their
label changed from Cd_pri;X, to Cd/H2/NonDeC;X. I checked the source for
all the rules and they shouldn't have N.

-"Ct_pri" was previously changed to include N. A child underneath it
"Ct_rad/Ct"", is it's previous definition without N. 7 rules had their
label changed from X;Ct_pri, to X;Ct_rad/Ct. I checked the source for all
the rules, and they shouldn't have N.

-Also in the rules with Ct_rad/Ct, I changed C to Ct, which is true by
 definition

-Changed definition of "N3d/H/NonDeC" in the rules to match the group's
definition. The groups.py definition was more specific and corresponded
better with the label. (affected 5 rules)

-Created new group O_rad/OneDeC, underneath O_rad/OneDe because
O_rad/OneDe was expanded to include N, but there are rules that only use
C. Changed the name on the relevant rules, and moved some children
(O_rad/Cd and all it's children) underneath the new O_rad/OneDeC node

-Because of above change, O_rad/Cd and all it's children had C atoms
changed to Cd or {Cd,Cdd}
