Integrate JBrowse.

NOTES

Included for testing.
* MAKER2 generated gene prediction in GFF3 format for two scaffolds of
  fire ant genome.
* Gene prediction for the two scaffolds of fire ant genome in JB/JSON
  format.

localhost:9292/#/genome hosts a working instance of JBrowse with a
navbar on top.
* Compiled JB's CSS into one genome.css. Styles from Dojo libs are
  'imported' from app/src/vendor.

TODO

* Remove JB's tracklist / sidebar.
* Add Next button at the bottom.  Clicking Next moves to next genomic

* JB shouldn't set page title.
* Remove 'Full View' link.

  This is going to be giganormous amount of work. What I want here is
  ...
  If possible, use fonts-awesome instead of JB's icon set.

* Rewrite JB's Perl scripts in Ruby.
  * contents of data/jb should not be a part of the repository
