Problem/Motivation
When using the timeago formatters on datatime fields, the setting summary does not display properly on the Manage Display page. This was likely a side effect of #2500525: Time ago/hence date/time formatting breaks caching; needs appropriate max age. The setting summary also does not with the timeago formatters on timestamps.
Proposed resolution
- Refactor DateTimeTimeAgoFormatter to extend TimestampAgoFormatter
- Fix settings bug with TimestampAgoFormatter
- Fix settings summary for TimestampAgoFormatter and DateTimeTimeAgoFormatter
