Added a check whether the elements in the molecular formulas are covered in the dbe calculation to convert strange error to explicit error

Added 11 additional adducts: [M+K]+, [M+ACN+H]+, [M+ACN+Na]+, [M+2Na-H]+, [2M+H]+, [2M+K]+, [2M+Na]+, [2M+NH4]+, [2M+ACN+H]+, [M+ACN+2H]2+, [M+2H]2+

Added the optional export of invalid spectra to records; added the export of the preceursor-intensity into records; added the export of generic AC and AC information into records

added fix to keep the properties of child-spectra valid and a minor fix to aggregate spectra without error

Attempt to fix error I just encountered in https://github.com/MassBank/RMassBank/issues/112

Attempting a fix at the RDB error messages caused by presence of As, Hg in SMILES
