external sugarjs was not the same package as development

In `app/assets/javascripts/external/sugar-1.3.5.js` there is a full development package of Sugar, however `external_production/sugar-1.3.5.js` is *default* minified build, which lacks a few things. Mostly international date formats, which Discourse now uses (or will use). Try this is a javascript console:

    Date.create().format("short", "fr")

This gives you the correct French (13 mars 2013) format in development, but fails in production.
