Configured the Foundation initialization script to run in noConflict() and default mode

The purpose of this commit is to facilitate Foundation running in jQuery noConflict() mode in which the $ shorthand is globally replaced with the "jQuery" long-form function name. The commit supports running in noConflict() and default ("$" shorthand is available) modes.

I tested in both modes using the code referenced in the [Getting Started Guide] (http://foundation.zurb.com/docs/) and the [Top Bar Guide](http://foundation.zurb.com/docs/components/top-bar.html)
