Add a "wireless" link from the Node Status page.

Remove isadmin() restriction from floormap pages; at some point I
assume we make the floormaps publically available.

Make MEB the default argument to the floormap page until such time
that we need something fancier.

Add a link to the wireless tutorial I am currently throwing up onto
paper.
