Get us some nice auto translation scheme

First things first, I'm not sure I'm setting the right variable on
the setlocale() call, so someone more knowledgeable can look at it and fix it.

How this works, you say? Just like elm_object_text_part_set(), except now it
will pass the string given through dgettext() with the given domain (NULL
means it uses whatever the app set with textdomain()), and when changing
language with elm_language_set(), it will re-set the strings with a new
translation.
