R2DT fails with complex header lines

[blakesweeney]

It can't handle some complex header lines like:

>DB|TEXT|MORE Some nice name

It seems that having several | characters causes esl-sfetch to fail with:

Creating SSI index for /rna/r2dt/temp/sequence.fasta...    done.
Indexed 1 sequences (1 names).
SSI index written to file /rna/r2dt/temp/sequence.fasta.ssi
sh: 1: TEXT: not found
sh: 1: MORE: not found
seq DB not found in SSI index for file /rna/r2dt/temp/sequence.fasta

A complete fix of the issue is to transform all fasta headers to something that will always work (1, 2, 3) and then run the steps on this transformed file. Before creating the final results for the user all ids should be replaced with the original ones.
