updated Docker build to fix perl locale problemfound dependency issues that had broken the Docker build
so fixed them too
also changed the build so example FASTA files are copied from
the repo where the docker build is done (so that if these files are
changed in a branch/tag, that's reflected in the image that is built
rather than always referring back to the master branch on github)
