Add upcoming Localization Hangouts to the blog events calendar

Hi @emmapeel, your latest mail to torproject (https://lists.torproject.org/cgi-bin/mailman/listinfo/tor-project) reminded me that it would be great to have upcoming Localization Hangouts on the blog events calendar. Could you add them, maybe the next 6 months worth? This really helps with getting it in the newsletter, more play on social media, etc.
