Add example for moving files

[tmcw]

It's relatively simple to move files with knox, but it requires you to set Content-Length: 0 so that nodejs doesn't send a Transfer-Encoding header to S3, which will make S3 501.

Adding some documentation for this might save people some time:

client.put('0/0/0.png', {
    'Content-Type': 'image/jpg',
    'Content-Length': '0',
    'x-amz-copy-source': '/test-tiles/0/0/0.png',
    'x-amz-metadata-directive': 'REPLACE'
}).on('response', function(res) {

}).end();

Should we maybe have a move higher-level method?

[tmcw]

Possibly; along with list for sure, down the line, although the lack of a good xml library for node makes that area a little shaky for now.

yeah sucks they dont have a json api

Rather cruddy implementation of a listbucket method, fwiw: https://gist.github.com/736504
