vsearch runUblast incompatibility

[Former user]

presto.Applications.runUBlast -vsearch v2.4.2 no longer supports usearch_local (but there is usearch_global) -see https://github.com/torognes/vsearch/issues/206 for this vsearch bug which means that giving vsearch sequences with '-' will result in stder

@ruoyijiangyale is that you making issues without logging in? :P

IIRC, vsearch has never supported usearch_local. I don't think we can work around that. The solution I went with was to implement blastn support for those tools that needed local alignment.

vsearch doesn't include local alignment support, you need to use blastn instead.
