Topological subcategories of Action V G

For a concrete category V, where the forgetful functor factors via TopCat, and a monoid G, equipped with a topological space instance, we define the full subcategory ContAction V G of all objects of Action V G where the induced action is continuous.

We also define a category DiscreteContAction V G as the full subcategory of ContAction V G, where the underlying topological space is discrete.

Finally we define inclusion functors into Action V G and TopCat in terms of HasForget₂ instances.
