Admin: headings without lectures; "Saved layouts"

The Theme, Modules, Available modules and layouts sections each opened with a
paragraph explaining themselves. The controls explain themselves; the
paragraphs are gone. The one line that carried information — where settings
are saved on this machine — stays. "Named layouts" becomes "Saved layouts",
which is what they are.
