Investigate warnings from QCommandLineParser (caused by some paritaly implemented features)

[pktiuk]

After running antimicrox we get warnings from QCommandLineParser informing about checking not defined options.
These are caused by some partialy implemented features

antimicrox --log-level info
❗WARN  QCommandLineParser: option not defined: "next"
❗WARN  QCommandLineParser: option not defined: "map"
❗WARN  QCommandLineParser: option not defined: "display"

Code adding them to commandline is commented. I don't know why.

        {"display",
            QCoreApplication::translate("main", "Use specified display for
            X11 calls")},
        {"next",
            QCoreApplication::translate("main", "Advance profile loading set
            options")},
         {"map",
             QCoreApplication::translate("main", "Open game controller
             mapping window of selected controller. Value can be
             a controller index or GUID."),
             QCoreApplication::translate("main", "value")},

TODO

Investigate these features and fully enable (finish/fix) them or remove them from code.

I think it would be good to just remove these flags with linked code.
These functions are too specific, and nobody was missing them.

Use case of the --next flag was mentioned in this discussion: #774

I have no idea what was behind commit e2a35d0 which disabled --next flag. Maybe I could re-enable it and check how it will work
