CppEditor: Quick fix "Insert (Pure) Virtual Methods"

This quick fix inserts (pure) virtual functions of base classes to the
current class. For selecting the functions which should be inserted and
for choosing the insertion mode (only declarations or with definitions
inside, outside or in the implementation file) a dialog is shown.
