Jobs listing improvements

[benlk]

Using https://inn.org/job/senior-reporter/ as an example:

Can we:

• remove the small square logo beside the employer name
• remove the byline
• move the posted date somewhere else
• make the expiration date visible
• remove the background color behind the listing image

Note: This is my personal nitpicks, not a request from someone else. We might want to incorporate design aspects from the recent Current business directory redesign.
