Page rendering fails if translation file contains certain empty header tags

[Tar-Minyatur]

Looks like some PO file editors insert additional header tags that raise the expectation that a date value is included there. The Babel library used to parse the PO files sees these missing values as error and throws an exception.

I didn't look into it very closely yet, but it can easily be seen if you run the render.py right now. It prints:

Rendering templates\together-we-are-powerful.php
	...
	⚠ Failed to generate for es-MX: time data '' does not match format '%Y-%m-%d %H:%M'

A quick look at the relevant PO file shows that there are header entries called POT-Creation-Date and PO-Revision-Date, which are not present in the other translation files.
