Merge pull request #591 from hzeller/virtual-override 
Consistent use of 'override' for virtual methods in derived classes.

Clifford Wolf e275692e84 Verific: Produce errors for instantiating unknown module 
Because if the unknown module is connected to any constants, Verific will
actually break all constants in the same module, even if they have nothing
to do structurally with that instance of an unknown module.

Henner Zeller 3aa4484a3c Consistent use of 'override' for virtual methods in derived classes. 
o Not all derived methods were marked 'override', but it is a great
  feature of C++11 that we should make use of.
o While at it: touched header files got a -*- c++ -*- for emacs to
  provide support for that language.
o use YS_OVERRIDE for all override keywords (though we should probably
  use the plain keyword going forward now that C++11 is established)
