Subject: Fix ClipboardChangeObserver

The meta type for QClipboard::Mode must be registered, because we're
passing it from the application thread to the IO thread.
Without this registration, one can trigger Qt metaobject warnings by
alternating between copying text and copying images to the clipboard.
