Review the use of datetime.date().today in schooltool.

[Ignas Mikalajūnas]

datetime.date.today() returns the date that matches the timezone of the server,
though we should use tz.localize(datetime.datetime.utcnow()).date() to get the
"today" of the user and datetime.datetime.utcnow().date() to get the UTC today.

This still in progress ;-)

[Justas Sadzevičius (justas.sadzevicius)]

I have a hunch that it is not that much in progress now.
