Automatic observer and system registration

[mrchantey]

Its very difficult to remember to register each action for a given scene, and its also hard to know which default ones are registered by the LifecyclePlugin

We should add typeids to a hashset on register, and check that set on add with lifecycle hook. If its missing id like this to panic by default, with options for warning or ignore. I cant think of a use-case where its a desired configuration.

Im changing the scope of this issue to automatic registration instead of panicking. The reason we can do this is an action Component is inseperable from its observers and systems, its different from vanilla components, observers and systems that have much looser relationships.
