me-web? 0.15.4: a desktop with a wireless mouse is no longer taken for a laptop

- On Linux, a desktop computer with a wireless mouse, keyboard, headset or game controller was described as a
  laptop, with the advice to use a small always-on computer instead, because the battery inside the mouse was
  counted. Only the computer's own battery counts now.
- The mail card now leads with what big mailboxes care about most: when your address's reverse name looks like a
  home line, or there is none, that comes first. A blocklist that names your provider's whole network is still
  shown below it.
