[EMBOSS] Updated dbx* applications

[ajb at ebi.ac.uk]

These applications have been rewritten to cope with an unlimited number
of duplicates (e.g. EMBL WGS file accession numbers). The replacement
files are now on our ftp server.

   ftp://emboss.open-bio.org:/pub/EMBOSS/fixes/

Look at the README file in that directory to see which files you need.
Some speed-ups have also been added and the programs now honour the
directory settings in emboss.default.
