Easier Multithreading
v0.1.5 had unintended consequences on non-multithreaded systems. In this release, we fix that! Instead of requiring send sync for absolutely everything, now send + sync is only required for components being accessed or added in multithreaded functionality.
Renaming
We made a slight adjustment to the name of the "GameEngine" struct. That name doesn't accurately represent what it is, it is a ecs not a game engine. So "GameEngine" has been changed to "World" to better reflect functionality and purpose.
