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.
