Add a top-level /data with static.File(DATA) that serves files from the data directory

[sagetrac-acleone]

Instead of having /js, /css, etc, we should serve all static data files out of /data. For now this patch just adds /data using child_data = static.File(DATA), where static.File(path) is defined in twisted. It will serve files with the correct MIME type based on extension.

Eventually we should find all the /js and /css paths and change them to /data

At some point in the future we could even implement caching of all the static files easily by subclassing static.File(path), and making everything in /data cached.

Not a patch bomb.

Changes the url to /static/. Replaces previous.

The latest patch changes the url to /static/.

I think we should also rename the "data" directory in the sagenb source to "static", and rename the global DATA to STATIC.

DATA is slightly confusing because uploading files to a worksheet also uses a DATA global, eg DATA+'mydatafile.txt'.

Ok - ignore the new patch. Let's leave the url as /data.
