Visually distinguish the timestamp in a status stream entries & comments from the text body

Not doing so can lead to odd outcomes.

For example, here's an entry by Kieran commenting on someone's post. It almost looks like the "18 hours ago" is a continuation of Kieran's comment (e.g. he was on the mountaintop 18 hours ago.)

Use a different font color, size, or positioning to distinguish the timestamp.
