search for gziped cache if uncompressed cache is not found

[weiribao]

For return=data, if the file is not found on disk, try filename.{out,data,datax}.gz. If the request had accept-encoding: gzip, just stream the gz file.

Options

(1) Redirect request to static file visible through Apache (or use Node.js to redirect)
(2) Modify getcachedata in util.js so it reads and uncompresses content. (May be a problem if user requested compressed response.) Or have getcachedata set a flag that tells app if what it is being passed is gzipped. Or have getcachedata respond with pointer to file.
