sgit -e 's/web site/website/g'

A choice was made a while back to use website and not web site so
changed all new references of 'web site' to 'website':

    sgit -e 's/web site/website/g' '*.md' '*.html'

As this also occurs in the FAQ and there were some minor mods (just
textual, including some fun, not a new FAQ) these are included too.
