Title: Add a filter to optionally toggle the display of of long meta values.

This may be more of a personal preference, but many of the meta values we have (for example related articles) are very long, and the majority of the time aren't of any interest.

This adds a filter which allows a developer to set an arbitrary maximum length for displayed values. Any value longer than that length will be replaced with "Click here to show…" Clicking that element will show the hidden value and hide the "Click here" element.
