 (Please refer to Pull Request: MRO of DeleteView was changed)

 I think MRO of DeleteView need to be changed in order to clarify the
 inheritance hierarchy.
 So I refactored BaseDeleteView and DeleteMixin.

 * (1) What is better as the super class of BaseDeleteView ?
   * Currently BaseDeleteView inherits from BaseDetailView.
   * I think SingleObjectMixin is sufficient.
   * I think Inheritance of Mixin is better than generic view itself.
   * So I deleted BaseDetailView in the super class of BaseDeleteView.
 * In order to inherit SingleObjectMixin instead of BaseDetailView,
   * BaseDeleteView inherits from DeletionMixin.
   * DeletionMixin inherits from SingleObjectMixin.
 * (2) Where is better on the location of get(), post(), delete() methods ?
   * Currently DeleteMixin provides those methods.
   * It is bad that Mixin class provides those methods, I think.
   * So My change is that BaseDeleteView provides get(), post() and
 delete() methods.
