Update the daily inputs total time dynamically
I suggest to update dynamically (as the user enters values) the total time for the day.
I also suggest to put the saved amount as tooltip for reference.
I made code changes to do that, I attached the Hg Diff file if you want to use it.
Note that the diff file also includes new strings related to proposal #1319 and a few changes I made in French according to my perception of good translation.
