Non-standard environment variable priority

[giomasce]

Current Boost.Locale code uses, in this order, environment variables LC_CTYPE, LC_ALL and LANG to detect the default system locale. This is different from the standard behaviour, which is to use, in the order, LC_ALL, LC_* and LANG (see, for instance, the POSIX reference).

I think it would be great for Boost to adhere to the standard behaviour.

This bug was first reported to the Debian bug tracking system: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=893884

Please see patch #22. Note that that is minimal fix, it just switches LC_CTYPE and LC_ALL. The best fix is to create each facet with its matching environment variable, not just with LC_CTYPE.

#22 was closed, this should be closed too.
