Add organisation link to finder

In order to display the organisation Metadata, we must tag each Finder in Panopticon with it's Organisation and fetch this on load.

This PR displays a link back to the Finder's tagged Org. It also styles it to look like the metadata in the rest of GOV.UK and adds a CSS reset to fix some browser stylesheet margins going on. I also fixed a spacing issue this introduced on the Filter Results button.

This PR also sets the title of the Finder from the Panopticon Artefact and removes the empty breadcrumb trail that just says "Home". 

Most of these changes require the Panopticon Artefact to have the Organisation tagged and all the information correctly set.
