Seqpeekv2 integration

Changed to Mutation Map to use the latest SeqPeek V2 code from https://github.com/IlyaLab/SeqPeek/tree/development

The view uses a visualization builder that inserts the SeqPeek visualization into DOM elements that are created in the view and template(s).

Added a row to the view template for displaying coordinates below the SeqPeek tracks.

The SeqPeek dependency is included in bower.json.
