gzipme module is of low quality, does not catch errors at all (throws hard exception and bombs app)

We will need to remove this in favor of using gzip streams properly, no npm dependency needed, although we could simplify it to a gzipme.js of our own with the same API plus a useful callback that implements error reporting.

  var out = zlib.createGzip();
  fileOut = fs.createWriteStream(filename);
  out.pipe(fileOut);
  // listening for both finish and errors properly, pipe aread stream into out

This is a blocker for releasing azure.
