modified version of dump_genebank script to dump annotated scaffolds for Genbank - as used for v38 db and AgamP3 geneset 3

removed BOUNDRY CROSSED error message as this is not needed. The feature is ignored if it goes past a PER boundry for example but this is supposed to happen

Corrected error in Aedes aegypti insert into source was missing the last column value, and fixed ftp://ftp.ncbi.nih.gov/refseq/release/fungi/ download, I removed the files bigger than fungi12.* as they no longer exist

New prioritys can be used with xrefs to allow one source to have many different inputs each having a different priority. Also gene descriptions etc are not just based on the mapping done but on all those in the object_xref tables etc, so it is also possible to just recalc descriptions or display xrefs

added prioritys to the xref sources. This is the priority that they have for each accession for a particular source. This id completely different to the order.
