GTF support

A useful comment from a forum thread:
"The whole point of the GTF format was to standardise certain aspects that are left open in GFF. Hence, there are many different valid ways to encode the same information in a valid GFF format, and any parser or converter needs to be written specifically for the choices the author of the GFF file made. For example, a GTF file requires the gene ID attribute to be called "gene_id", while in GFF files, it may be "ID", "Gene", something different, or completely missing. Hence, a general GFF-to-GTF converter (as opposed to one converting only GFF files from a very specific source) needs to guess this from the data, which is non-trivial."
