script: contribute "light" theme overrides

Add script-theme.{c,h} with the script plugin contribution to the
built-in "light" theme: 24 entries on script.color.* (status_* and
text_*) tuned for a light-background terminal.

Same 2D-array pattern as the other plugin contributions.

Default option values are NOT changed.
