Router no longer works with 0.8.3 because Templates no longer have the .extend function

[Dsyko]

The .extend function used on line 10 of /lib/router_helpers.js is no longer available in Meteor 0.8.3 causing the Router to throw an error an nothing gets rendered.

You can get around this issue by doing the following:
Replace use of the {{> renderPage}} helper with {{> UI.dynamic template=currentPage}}.

But you should probably change over to Iron-Router when possible.

Now:

{{> Template.dynamic template=currentPage}}
