Add missing files from app repo

[dereuromark]

When upgrading existing apps, maybe the upgrade shell can put missing files and folders into the app.

E.g.:

/logs
/bin/cake

etc.

I would also add replacing index.php and webroot/index.php. Also dropping in a default config/app.php might be nice.

If not yet created, of course.
Sounds good.

Shall we call it "skeleton"?

Sounds like a good name to me.

Looking at how the code currently works, it seems it always runs subcommands on all files.
We would in this case only need the base (app root) path - and not a file itself.
Can we somehow tweak this in without having to change the whole upgrade shell?

Closing as #35 is open.
