Add Hungarian translation

[urbalazs]

Hi @tobiasd, I've just finished the Hungarian translations for the Friendica Directory and for the git landing page. You can find the translations on Transifex. Can you please pull the translations and deploy to be available online?

I have one more question: can you please promote me as the coordinator of the Hungarian language team?

The following addons are not in the "addon" category on Transifex: blockbot, catavatar, cookienotice, markdon, morechoice, securemail, viewsrc. Please consider to add them to the proper category.

Thanks!
