Document stdin & stdout capabilities in README.

Also, display them decoded in report.

For future serialisation support flexibility.

Require clicking to display in-table graphs instead of hovering.
Make graphs dragable (add a dependency on jquery-ui).
Move apachedex-specific javascript to a separate file.
Move apachedex-specific css to a separate file.
Lazily render graphs to speed-up page loading with many graphs.
Also, fix tooltip coordinates inside positioned blocks.
Also, apply formatting to tooltip y coordinate.
