Add plain-text description to each permit in Socrata data set

Almost every permit has "Test description of permit", e.g. "Development Plan Review". Before we can launch, each permit needs a plain-text description so the user knows what each permit is for.

@samanthawolfe Nudge nudge. This isn't blocking us from working, but we'll need to spend some time collectively poking all the site with a stick to see what content needs to be updated in prep for golive.
