new NCBI Nucleotide web translator

Using the Entrez Eutils JSON API. This is a translator for datasets, and therefore has some limitations, e.g. apparently no author information.
GenBank format, I think, is generally more useful and the overhead is minimal. E.g. http://eutils.ncbi.nlm.nih.gov/entrez/eutils/efetch.fcgi?db=nucleotide&retmode=gb&rettype=text&id=2695690

Though I can see how FASTA is simpler and maybe more approachable, so I'll leave that call up to you.
