Add localization functions

[technosophos]

It would be nice to add localization functions. Not sure how it would all be composed, but something like:

t "FR" "cheese" -> "fromage" would be nice.

It would be particularly nice to be able to set a "global" language and translation strings facility and then be able to just call t "cheese". This is how Drupal does it.

The backend would need something like:

type Translator interface {
  T(string) string
}

An easy map-based backend could satisfy that interface.
