added bromine analogues

I was asked, if it is really a double bond or maybe a radical: HOMO and LUMO, pi and pi* of the DB, are separated by more than 2 eV (except for TBNBL II, where it is 0.23 eV). I'll leave TBNBL II in the answer, because it shows my working process, but I guess it is actually no DB. | |
