Adding Thermo for alpha radical from ethylamine

RMG was predicting the H298 to be 10 kcal/mol less stable.
Adding HBI for Carbon centered radical with neighboring N atom.

These are based on CH3CHNH2 cbs-qb3 calculations, values for secondary
and tertiary are estimates.
Correcting typos in previous commits!
More fixes to the last commit

RMG-Py data structure is non obvious that it was really hard to see the mistake!
Suprisingly RMG-Py did not crash but just went into endless loop.
Adding thermo for more radicals formed from ethylamine
Accomodate both 2T and 2S in Ybirad for SubstitutionO group.

This fixes RMG-Py not finding reverse reactions due to spin issues.
