Systems now place all of their component factories into a `Components` member. This improves code readability and makes it clear when we are dealing specifically with ecs components. The concrete ComponentFactory instances now have `Add` and `Get` methods (as opposed to `AddAlpha` or `GetAlpha`). This enforces naming of component factories as to avoid collisions when embedded in a struct with other components. Also, the ComponentFactory interface is embedded directly into the concrete component factory without a name.
