Add an model_subclass generator.

This generator creates a new model as a subclass of an existing model and the unit test for that model.  Lets users avoid having to manually delete the fixtures and migration or remember to pass those arguments.

+Description:
+    Create a model subclass of parent, used for Single Table Inheritance.
+
+    Both subclass and parent name can be either CamelCased or under_scored.
+
+    This generates a model class in app/models and a unit test in test/unit.
+
+Examples:
+    `./script/generate model_subclass admin user`
+
+        creates an Admin model, which will inheritate from User model, test:
+            Model:      app/models/admin.rb
+            Test:       test/unit/admin_test.rb
