Is QtQuickComponents.MouseEventListener needed anymore?

[David Edmundson]

I was looking through MouseEventListener and trying to work out if
it's needed any more. As far as I can tell, all functionality that it
provides* is provided by Qt's MouseArea.

I assume it was added to work round a specific bug/missing feature in
Qt's MouseArea, but it's not clear what that was.

If it's needed I'd like to know why so I can document it and I'll
invest the time to fix the memory leak problems it has. If not I'd
like to port all usages away and mark it as deprecated.

*  The only exception is a screen property in the events that Aleix
and I added last week, but I can work round that elsewhere.
