Deprecated, QColorDialog is now cool.

Both are OK to use, depends on the use case
(KComboBox provides KCompletion support)
So, remove the krazy check.

> QMessageBox => KMessageBox

Both are OK to use. KMessageBox has additional features.
Remove the krazy check.

> QErrorMessage => KMessageBox

QErrorMessage is still a weird beast which doesn't save the "don't show again" 
to disk. So yeah, keep this check.

> QInputDialog => KInputDialog

Deprecated, QInputDialog is now cool.

> QFileDialog => KFileDialog

Deprecated, QFileDialog is now cool.

> QProgressDialog => KProgressDialog

Same.

> QSplashScreen => KSplashScreen

Same.

> QSystemTrayIcon => KNotificationItem

No clue. I can't even find KNotificationItem in KF5 anywhere.... !?!?
In fact it doesn't exist in kdelibs4 either.

I think it got replaced with KStatusNotifierItem since 4.4 ?
That one is still valid in KF5 (framework "knotifications").
I have no idea if/why it means QSystemTrayIcon is bad though.

> QDialog => KDialog

Deprecated, QDialog is now cool.

> QLineEdit => KLineEdit

Same as QComboBox: both are OK, remove check.

> QTabBar => KTabBar

Deprecated.

> QTabWidget => KTabWidget

Deprecated.

> QTextBrowser => KTextBrowser

Deprecated.

> QTextEdit => KTextEdit

Both are OK. E.g. KTextEdit provides spellchecking with its sonnet 
integration, but if you don't need that, QTextEdit is fine.

> QUrl => KUrl

Deprecated.

> QNetworkAcessManager => KIO::AccessManager

Still true, keep this check.
