Pictures in the tour are outdated and don't reflect the current state of floor

At some point when the semester gets going again, we should take some new pictures for the tour page. @rossdylan also has a cool photosphere of the server room that can be embedded on the page.

Floor needs to be in a more reasonable state, but I would like those to be updated.
