New upstream release. Changes:
* Add tooling for localized UI texts and Emoji names imported from
Unicode CLDR
* Add translations for German (de)
* Improve search, show groups (skin-tone variants of the same Emoji) in
search results and make it configurable what exactly the search looks
at: original and/or translated names, and whether or not to consider
other "variant" descriptions after a colon in the name
* Implement the _NET_WM_PING protocol and associated window properties,
allowing a window manager to know when and how to force-kill Xmoji
