Move to .html?

[Dan Beam, 2016/04/12 19:51:02]

bluetooth_add_device_dialog.html and bluetooth_pair_device_dialog.html both
import this file as well, BUT only bluetooth_add_device_dialog.html uses
.no-devices (which I'll fix up shortly).

tl;dr - Done.

-
-span.no-devices {
-  margin: 10px 20px;

positioned better by .list-frame
