Track Actor names better and improve add_actor

[banesullivan]

PyVista's BasePlotter tracks all Actors added to the scene with a unique name. This is a widely used feature and is tested quite well. Prior to this PR, the Actors themselves are unaware of their names, and I think PyVista's Actor class should track this value.

I don't like to add attributes that do not map to existing attributes/properties that exist in VTK, but in my opinion, this is a valid exception for a feature we've implemented specifically for PyVista.

Additionally, this adds support for explicit exceptions when using the @no_new_attr decorator. _renderer was a class attribute on Actor previous to this and I don't think it was actually working as expected. Through the use of _new_attr_exceptions, now classes can have a few explicit exceptions for new instance attributes like _renderer and _name for Actor
