Bug 378089

If I do code completion inside a class, it offers to override virtual functions in the parent class. However, the functions are simply ordered alphabetically. I think pure virtual functions should be offered first, since overriding them is *necessary* for the current class to stop being abstract.

Example:

class Base {
public:
    virtual void aaa() {}
    virtual void bbb() {}
    virtual void ccc() = 0;
};

class Derived: public Base {
public:
    // code completion here shows aaa, bbb, ccc
    // I think it should show ccc first
};

(btw, could somebody check what was the behavior in oldcpp, eg. in KDevelop 4?)
