Outliner could have a `hint` for static items.

The outliner in qt-creator is quite good, but I've found myself often scanning down for members which I know are either static (functions local to that file), or global functions which are in headers elsewhere.

I think it would be good to have some visual hint on the icons of static functions & variables. (grey out a little or a dot in the corner.. not certain).

Or, the ability to have static members first/last for eg, some way to show only one or the other.
