czech translation update

[Petr Marhoun <petr.marhoun@…>]

This patch translates all new strings. Everything except django.contrib.humanize and django.contrib.localflavor should be translated.

I also realize than I am three times between authors. This patch removes two of these three occurrences.

(In [8448]) Refs #8445, Updated Czech translation. Thanks Petr Marhoun

[Marc Fargas]

Commited, I do not have permissions to change AUTHORS so I'll leave the ticket open hoping Malcolm will see it and apply the change ;)
Thanks for the translation!

Any commiter going trhought this ticket:
The only thing pending is to change the AUTHORS file, removing:

l261:    Petr Marhoun <petr.marhoun@gmail.com> 
l306:    petr.marhoun@gmail.com 

Petr, your diff removed those two lines, do you want to be removed from the AUTHORS file?

[Petr Marhoun <petr.marhoun@…>]

I am mentioned three times in AUTHORS - my patch should remove two of these lines, one should remain. But it is of course very unimportant and I think this ticket could be closed.

[Marc Fargas]

You're famous then!! ;) I'll leave it open until tomorrow, maybe Malcolm sees it later. I didn't set the Milestone as it was not important ;)

(In [8461]) We value Petr Marhoun's contributions very much, but he should still only
appear once in the AUTHORS file. Fixed #8445.

Unfortunately the commit accidentally removed peter@… instead of petr.marhoun@…, I noticed this by a pure chance.

[Malcolm Tredinnick]

Yep. Good catch. Thanks. I'm an idiot.

Fixed in [8467]
