RdpDisplayWidget::keyPressEvent() dropped every event where
QKeyEvent::isAutoRepeat() was true, which discards the entire repeat
stream Qt generates while a key is held -- so holding a key only ever
produced a single keystroke on the remote machine. Auto-repeat presses
need to reach the remote server so it can perform its own typematic
repeat, exactly as a physical keyboard held down would; only release
events should filter isAutoRepeat() (kept as-is), since Qt uses a
synthetic release/press pair purely to normalize platform auto-repeat
quirks, and forwarding that synthetic release would send a spurious
key-up for a key still physically held.
