Port body part code from DDA up to May 4

ngettext wrapper + tests for changing language (cataclysmbnteam#401)

* Make talk_topic string extraction consistent between runs

* Remove <locale> include from output.h

* Add wrapper around ngettext(), rename npgettext()

Now all *gettext funcitons and _() macro are cata's wrappers.

This is necessary since even without explicit libintl.h include
<locale> header pulls in libintl.h on some platforms anyway.
This behavior cannot be disabled, and could lead to a conflict
between cata's ngettext and libintl's ngettext.

As a bonus, this allowed to remove <libintl.h> and <locale>
includes from translations.h

* Replace ngettext() calls with wrapper, rename usages of npgettext()

Done via find-and-replace

* Test that translations return translated string

* When testing, print lang switch related info via cata_printf

Because DebugLog() does not immediately append newlines,
and that makes the rest of the log ugly.

* Always print rng seed for tests

* Remove unused macro

Static linkage is either broken anyway (msys), or works fine
even without this macro (cygwin, mingw cross-compiled).

* Remove unneeded check in translation test

In this test we don't care if that's the original string,
just that the string is a correct translation.

Rename temperature literals to avoid cygwin conflict
