Export GenBank accession number to CSV

See request here to export accession numbers from GenBank besides the sequence name: http://ugene.net/forum/YaBB.pl?num=1580318066

The feature should be added as a new option when exporting annotation data to CSV and supported when:

• Exporting annotations in the Project View
• Using "Write Annotations" workflow element

Besides the GenBank format, it should be supported for other formats as well (PDB, SWISS-PROT, Ensembl, etc.) that have the data identifier.
