Lose dependancy on pytz python package

[Dries Desmet]

When e-mail messages were hard coded and not using Django's templating system, datetimes were not converted to the correct timezone, so we had to add this functionality through the pytz module. Now that the e-mail messages are stored in the database, we also make use of the Django templating engine. So pytz is redundant. Howver, at the time of this writing, the branch that fixes the "e-mail in databasse" issue #10 hasn't been merged yet.
