date filter returns empty string for midnight

[Danilo Bargen]

Python considers midnight (datetime.time(0, 0)) to be False. The date template filter stumbles over this.

When using {{ midnight|date:"H:i" }}, Django returns an empty string.

See ​http://bugs.python.org/issue13936 for discussion about the bug.

I'll post a pull request with the fix on Github in a short while.

This is already fixed in the |time filter, but not in the |date filter which can also be used to format times.

Regression tests are provided.
