Bugfixes (possibly breaking changes)

Changed getOrFetch() to dispatch its first action asynchronously. This addresses React warnings when multiple mounted components in the same render cycle called getOrFetch(), triggering an update to the state of a parent component.
getOrFetchList() now returns lists with a status of FETCHING immediately (rather than one with an undefined status)
Fixed empty JSON responses causing a client-side parsing error.

In addition to action creators, resources and resource now export dispatchers
Added a new saveItem() function for creating or updating a resource item based what state its currently in.
Added a getOrInitializeItem() function for automatically instantiating new resources not in the store.
getOrFetchItem() and getOrFetchList() can now be used with a localOnly resource, to maintain a more consistent interface when interacting with local resources and remote ones
Fixed TypeScript argument types for the buildInitialStatus() function for singular resources
Fix argument processing for defining localOnly actions
Added a new isNewItemkey() function for evaluating a value matches the one being used as the key for the newest item.
Added a new getHttpStatusCode() function for returning the HTTP status code of the last request performed on an item or list.
