It didn't feel right to have a "DHCPClient" in a "Servers" directory.
Rename this to Services to better reflect the type of programs we'll
be putting in there.
If the window switcher is up when a window is made frontmost (usually
by clicking on it), the window will now become the selected window in
the switcher.
This still has a slight feeling of "hmm" but is definitely better than
what we had before.
