[#241] Use proper names in follower success flash messages

Use user display names and group and package titles, not IDs, in "You
are now following..." and "You are no longer following..." flash
messages.
[#241] Tweak "You are already following..." flash messages

To make them consistent with the "You are now following..." and "You are
no longer following..." messages, just say e.g. "You are now following
{name}" not "You are now following dataset {name}".
