refactor source tree

[mblakele]

This patch rearranges the source tree along the lines recommended by Glenn Lewis at https://groups.google.com/d/msg/google-appengine-go/dNhqV6PBqVc/ihzI5vgdE1EJ and discussed at #320. All the go code stays where it is, but imports change to use full paths. All the non-golang assets move into a new app subdirectory: yaml, js, css, templates, etc. HTTP routes are registered explicitly instead of happening automatically in init(). I think this is a minimal set of changes, but there may be a better way.

With these changes, goapp test and goapp test ./... both work. The app.yaml file is now in the app subdirectory, so use (cd app && goapp serve) to start the app.

What is the benefit to moving the http routes out of init()?

[mblakele]

I might be missing something there: I found I had to move the init work into app.go or I'd just get 404s. I suspect setting up routes in imported inits just doesn't work with appengine and mux, but I haven't investigated.

Yes, you're right. I've gone ahead and used your ideas to accomplish this, so I'm closing it. Thanks for the work and links.
