[EMBOSS] NCBI Blast in emboss-explorer

[ajb at ebi.ac.uk]

Wrapping BLAST is on our things to do list for the medium term. I
believe at least two sites have attempted this in the past. At the
low level this is best done by splitting blastall into separate
applications as it fits better with exposing them as web/GRID services.
The blastall functionality can then be implemented as a GUI layer.
As for the short term, we'll be watching with interest!
