Real time widget and visitor log to display Time spent on page

[mattab]

Suggested in forum:

• in the real time visitors widget, in the tooltip that appears on the icon, display the time spent on the page (except last page for which we don't know the time spent)
• Also display the time spent on the tooltip over each page in the Visitor Log

perfect, can you please add in the tooltip "Time on page" then semi colon, prependded to the 165s

New translation can be created below this string in en.php:
'General_ColumnAverageTimeOnPage' => 'Avg. time on page',
