Brutally primitive webpage frontend

Committed comically, brutally primitive beginnings of a webpaged style
front-end for the REST interface that has been created. Current commit
only offers a very, very, very basic button to ping the /physical/status
url running on the local machine (pointing at localhost).

Enabled CORS support on the REST service (this is a cheap and dirty way
to make it so the dashboard can be nothing more than raw HTML opened
from the hard disk).
