recommend debathena-standard automatically if laptop-detect

[geofft]

There's a program named  laptop-detect, often installed automatically on Debian and Ubuntu systems, that will poke at DMI and guess whether it's running on a laptop. We should do something to the effect of

if [ -x /usr/sbin/laptop-detect ] && /usr/sbin/laptop-detect; then
    echo "Since you are running on a laptop, you should probably choose debathena-standard.
fi

to make the installation UX better in the common case.

Alternatively, we could pick a heuristic based on whether the network connection looks permanent (e.g., wired) or not (e.g., wireless), by, like, asking NetworkManager or something, since you basically never want anything other than debathena-standard unless you have a reliable Internet connection.
