Some build cleanup I did when I was trying to get things working. I'm not sure about kitchensink/dist instead of kitchensink/app. I'll ask about that in an issue.

Now the "kitchensink/dist" folder included instead of "kitchensink/app"
The BUILDDIR is now defined inside of the repository folder instead of /tmp for consistency.
The BUILDDIR now uses "mkdir -p" so that the intermediate directories are also created if necessary
