Pulled in some Unix-specific code from https://github.com/rust-locale/locale_config to reduce dependencies. First reason to reduce dependencies: gettext-rs is not in Debian. Copying gettext-sys might have made sense, but the interface is somewhat confusing. For translating a couple identifiers, detection and some hand-rolled hash map is all that is needed, and the option to move to gettext later remains. locale_config has been stripped of the lazy_static dependency, which, messing with the strtup sequence, might be a source of debugging woes. Plus setting language once in the beginning is somewhat inflexible regarding runtime changes.
