The intention is to replace the Handlebars expressions in the mojit archetype with lowercase strings so that the module naming convention will match the YUI module naming convention, which is used by the Mojito framework and the Mojito API's addons. 

While it was easier to lowercase the string within the `replaceCb` function, in retrospect, I'm sure there is a way to avoid lowercasing all of the replaced strings. I'll look for another way and am open to suggestions. Thanks for your feedback, Isao.
