all bridgy posts should have explicit p-name inside their h-entry

[tantek]

Currently bridgy posts typically have an h-entry without any explicit p-name. Thus by the microformats2 implied p-name rules, the entirety of the h-entry's inner text becomes its p-name which results in unexpected / undesirable UI effects, e.g. see backfed mentions on this event post: http://aaronparecki.com/events/2014/01/29/1/homebrew-website-club

All bridgy posts with h-entry (which is all of them I think) should have an explicit p-name that makes sense for that post, that a receiver could use to display a brief text summary of the post.
