New version of the Flowcell page.

So this is the PR for the new flowcell page. The couchdb view is not in production yet. Anyone know how to do that in a properly documented manner ?

Just had a look - you should be able to drop any new styles into [status.css](https://github.com/Galithil/status/blob/Flowcell_update/run_dir/static/css/status.css) and they'll be available..
