wmaker: Removed notion of 'Default' mouse cursor

A default cursor would make sense if we were talking about an API,
where we would propose a 'I-don't-know' choice to devs, but here
we're talking about WindowMaker's internal, where we're supposed
to provide a consistent interface to the user, so picking a
cursor is not an option (and 'Normal' is actually a decent
looking choice anyway).
