Move app.yaml to app.yaml.template and add app.yaml to svn:ignore in trunk/app.
Each Google App Engine instance needs its own "application:" ID, and this
should *not* be committed into the SoC SVN repository in trunk/app. (Individual
deployment branches *will* have app.yaml files with Google App Engine
application IDs in them, just not trunk/app.)
