Bug 6512: time missing from item circulation history

Bug 6512: time missing from item circulation history

Re-enables the display of the seentime in circ/bookcount.tt; a DEFAULT was set, but
the value was never actually called into the template.

This patch also moves the time to the right side of the date, and removes the ??:?? default,
because otherwise, it's just silly
