2.2

• Rollback a change introduced in 2.1 into Fragment's loader management that could rarely cause a ClassCastException. You need to ensure you are using the last version of support library to avoid any leak.
• Change the behaviour of the onStart method of the presenter: Now the boolean passed tells if the view has been created, rather than if it's the first time the onStart method is reached. This way, you know if you should update your view according to the presenter state more easily: If viewCreated is true, then your view has just been created and thus its state should be updated, otherwise the view has just re-started with its old state and there's no need to update it.
• Update README to mention the install script on MacOS.
