use uTransformers v0.2

Hi Kevin,

This updates the repo to use uTransformers v0.2. Was pretty easy, everything "just works".

I would like to update the churn sample app to, for example, allow inputting regexes in the UI...but I'll leave that for a separate pull request.
I think it's better to use a grunt-copy-rule and use the standard directory layout and then use a purely local file-reference (that assumes the typescript-src convention for all ts code).
