Option to show timestamp in Call History tab

[Vulpen]

The info already exists when you click the three dots > Show call details. Just bring it out into the main interface, so people can view it without clicking each call's details one by one.

So instead of just showing 06.04 below a call, it should show "06.04, 12:20" (or "06 April, 12:20", depending on user date settings)

If call grouping it enabled, it should show the timestamp of the earliest call.
