Add new front matter element: excerpt (#227)
* This commit adds the excerpt front matter element, to show an
abbreviated version of the definition in social previews. This
also includes the documentation updates to support this change.

* This commit adds @olvb's suggestion to use 'set' to define the
alert & preview combo, to avoid repetitive code

* This commit updates the preview text to only include the flag if
it's "avoid" – if the flag is "warning" or there is no flag, it
will not appear at the beginning of the preview text.
