Storage Rewrite (#6)
- add Snapshot with Take and Restore methods - remove World.Transfer - components can now be accessed via `ref` - clients should call World.Dispose when they are done with a World - rewrite ECS storage to use fewer classes - all ECS storage methods now exposed in World - removed filter callbacks - removed MessageWithEntity methods - various data structure optimizations Reviewed-on: #6storage_conversion
