Add support for user-configuration language tag specification. (#1038)

Browse Source 
Adds a new top-level configuration key called "language":

```yaml
wtf:
  langauge: "ja-JP"
```

Users can now define which BCP 47 language tag to use to format any
text or numbers that currently support localization. Defaults to
"en-CA".

Acceptible values: any BCP 47 language tag recognized by the Go
"language" package.

Good luck to you figuring out what that cannonical list is. After a
morning of trying to suss it out, I have no idea.
