Add locale(1). I have used it for while as useful debugging tool
for locale related things. So, I think it could be useful for
others. It's not yet implement (or implement in different manner)
all POSIX things, but I think it's good enough for start.
POSIX conformance related updates and manpage to follow relatively soon.
