Add Tickable interface (#1790)

Browse source 
* Add Tickable interface

By having a tickable interface, we're only dedicating one thread to ticking entities and running tasks as opposed to several. This will also help with implementing world border support.

* removeEntity already clears tickableEntities for us

* Only tick the entity if it's not being ticked
