redbiom now adds per sample studies to analysis

While working on this I realized that format_biom_rows was duplicated with similar functionality so decided to merge them. Also that qiita_pet/templates/artifact_ajax/artifact_summary.html should be an input and not a link so the js works as expected.

Code looks good, but tests are failing.
