Update Getting Started guide page "Adding a Route and Template" to
remove outdated references to JS libs.

As the libraries are added in the previous page ("Obtaining Ember.js and
Dependencies)[1], the references here are unnecessary and also
out-of-date (the files downloaded have specific version numbers, i.e.
"jquery-1.10.2.min.js").
