This is wide but relatively shallow update that makes `World` only ever require `&self`, allowing us to remove the system initialization stage that was necessary to have `&mut World` access for initializing resources and components. The main change was to allow `Resources` to have resources added to it with only a `&self` reference by using a `once_map` internally. This meant that all resource cells now become `Option<SchemaBox>` on the inside. This conceptually means that cells for reasources are lazily initialized and always considered to be present, but they may or may not actually contain a resource value.
