Switch to local Unscii font and begin work on new stylesheet

Remove Google Fonts and the old external stylesheet link. Add (inline for now)
@font-face rules for unscii fonts and new link/p/ul styles, and set the
root font to unscii16. Minor UI tweaks: style the skip link background,
remove the "Tools" nav item for now, fix the contact page title and link
markup, and replace the homepage copy with an "Under Construction"
message.
