Help option failed when Olive was run in its own directory as strrchr
failed. If all else fails basename is equal to argv[0] and we don't
increment in the print statement. Tested on Windows 7.
QApplication is designed for GUI/widget programs and thus fails to launch
if no window system is available. For a true headless mode, we must swap
out with QCoreApplication. However, what complicates this is that
QCommandLineParser - the class we use to determine whether we should run
in GUI mode or not - requires an active application instance to work.
This creates an unfortunate catch-22 that ultimately ended in writing a
custom command line parser.
Now we can correctly swap out with QCoreApplication, however this has
exposed other issues regarding functions that unnecessarily rely on QWidget
functions. So they'll need to be sorted out eventually.
