Set language from LC_MESSAGES, not LC_CTYPE

Calling `locale.getlocale()` checks LC_CTYPE, which is not meant for
UI strings. Change the call to check LC_MESSAGES instead.

Also call `locale.setlocale()` first to import the locale settings
from the environment. This is not needed for LC_CTYPE due to
https://bugs.python.org/issue6203 but is required for LC_MESSAGES.

Closes #361
