Title: Small fixes of different classes comparison and not synchronized usage of SimpleDateFormat

In ChemCompTools:209 and ChemCompTools:221 different clases are compared, so it comparison result is always false. Changed type of ChemComp.one_letter_code field to Character as well, because it better describes its content.
SimpleDateFormat class is not thread-safe, so external synchronization is required for usage in multiple threads.
