Title: Ensure `packages.zip` is cleaned up properly

* Previously, it wasn't being deleted, so files were only being added or
updated, never removed
* Also, enable using non-zipped "packages" directory for experimenting
with deployment efficiency (e.g., appcfg.py will precompile Python,
but probably not inside zip files.)
