Add support for PUT & POST to qget test

Due to some bugs that are not reproducable with a normal HTTP GET
This patch also adds the option to process multiple URLs
serially (using application level queuing) rather than the default
parallel (using QNetworkAccessManager queuing on 6 TCP connections)
& renames the authentication command line options to match wget.
