[AI2 offline] Where are the projects stored?

@vknow360 is correct. The GAE dev server creates a datastore in appengine/build/war/WEB-INF/ where the contents are stored. In most cases I believe the keys are base64 encoded, so you can decode them to determine the exact file names. Note that we store the server side data as individual files, not as an AIA. The AIA is for convenience when exporting projects to not have to deal with passing around many files (it's just a ZIP file with a different extension).
