Allow blastprotein command to use a UniProt name or id

[Tom Goddard]

Would be convenient if the blastprotein command could take as the first argument a uniprot name

blastprotein MELB_ECOLI

or uniprot id

blastprotein P02921

It could do a web query to fetch the sequence or just run command "open MELB_ECOLI from uniprot".

​This was implemented today, but there is now a little bit of duplicated processing in the AlphaFold and blastprotein bundles. Still, I tested the AlphaFold search command and it is working.

[Tom Goddard]

I'll look into making the alphafold search command not convert uniprot name to accession code if the blastprotein command is doing it.

[Tom Goddard]

The alphafold search command does not run the blastprotein command.   Instead it creates a BlastProteinJob directly using the explicit sequence.  So there is no   code duplication to remove unless we want the alphafold search command to invoke the blastprotein command.  I don't plan to do that.
