Need a better definition of Systems and components

[BenjaFriend]

Right now the engine component model is somewhat monolithic and does not provide a clear path for users to go about making a new system.

I think the best way to go about solving this problem is to actually introduce the concept of System's into our data model. The engine will manage the lifetime of these systems for you, giving you a couple options to choose from when creating one.

Definitions

1. A WorldSystem - A world system will share the lifetime of it's owning world, being started and destroyed when the world does. By sharing the lifetime of a world this makes it easy to write gameplay systems, silar to Unreal's UWorldSubsystem and Unity's "Press Play" ideology.
2. A PersistentSystem - A system that will share the lifetime of the engine as a whole. It will be started when the engine is launched, and shutdown when the application closes. This is what the engine itself can use to do things like rendering, input, and other systems that need to be about during the entire lifetime.
3. EditorSystem - A system that shares the lifetime of the editor, which will make it simple to have some debug systems that you can create tools in and exclude from development builds.
