Release Candidate for v1.1.0

@Raizlabs/maintainers-ios 

### Changes

- Added a utils category with a new method to get an instance of an object in a different context
- Move the entity name helper to the utils category
- Add option to always create unique instances on import for objects with no primary key (`+rzv_shouldAlwaysCreateNewObjectOnImport`)

### Fixes

- Direct import to an instance using RZImport extension would previously fail due to unknown managed object context.
   - Add other method signature to support a context argument
   - Override original method to behave correctly via direct call or internal call (ongoing import)
- Support import of an array of object dictionaries into an ordered to-many relationship set
- Fix objects in main context not getting refreshed when merging notification from background context save
   - Obtain permanent ID's for all objects inserted into background context upon receiving `willSave` notification
- Only log warning about no primary key once per class
There are a few `[self class]` in class methods in this file as well.
