Inconsistent boilerplate at top of files

[petervanderdoes]

The license at the top of each *.py is inconsistent.

• Some don't have the license boilerplate wger/email/migrations/0001_initial.py
• Some don't have the line # along with Workout Manager. If not, see <http://www.gnu.org/licenses/>. in the license part
• Some don't have the correct file encoding line # -*- coding: utf-8 *-*

Anyway as you can see it's inconsistent throughout.

Suggestions

• Fix the encoding line for all *.py files
• Have a consistent license boilerplate throughout. Unless you want to get rid of the boilerplate which is ok with me as well.

Suggested License Boiler Plate

Use the boilerplate as suggested by the AGPL license itself

Yeah, there is no boilerplate at all in generated files such as the migrations, which is probably fine. As for making the header more consistent as well as the encoding (is this still important for python 3?), I'm all for it. We can use the text you suggested, I'm not sure where I got the one I used, I could have sworn it was from the gnu.org site as well.
