Interpolations not working

[brian-c]

Seems to be unable to interpret %(key) here:

https://github.com/maritz/node-sprintf/blob/master/lib/sprintf.js#L199

I noticed that npm's sprintf module is deprecated in favor of sprintf-js. Haven't tried swapping it in, but it's probably worth a look.

To reproduce in Node,

counterpart = require('counterpart');
counterpart.registerTranslations('en', {foo: 'Foo is %(what).'});
counterpart('foo', {what: 'cool'});

results in

Error: [sprintf] %(what).

You are using the wrong placeholder format. Instead of %(key) you have to use %(key)s. Notice the s at the end.

Totally missed that. Works fine. Thanks!
