Feature request: add number of views of a single job to the job listing

Similar to #581, I think showing the number of views jobs are getting would be a great way to encourage folks to share jobs and show the value in doing so. cc @dd32

We don't currently have any analytics on the site, so I'll start by installing Jetpack, but I'll need to get access to the CPanel first to update PHP to a supported version.
