Description: add missing virtual destructors
  GCC gives the following warning:
  deleting object of polymorphic class type KObject/KikiCharacter which has
  non-virtual destructor might cause undefined behaviour

  Fix this by adding empty virtual destructors. The warning is probably
  spurious for KikiCharacter but better safe than sorry.
