Long live QCommandLineParser!

The QCommandLineParser class provides a means for handling the command line options.

QCoreApplication provides the command-line arguments as a simple list of strings.
QCommandLineParser provides the ability to define a set of options, parse the
command-line arguments, and store which options have actually been used, as
well as option values.
