$inject function handlers

[joeljeske]

It would be very useful for function handlers to be injected instead of called directly. Especially when the functions need to be used in a provider context, it makes using services awkward.

Usage Examples:
Usage in Permission defintion

PermPermissionStore
   .definePermission(name, 
      /* @ngInject */ function($myService, permissionName, transitionProperty) {
       ....
   });

Usage in State definition

permissions: {
  only: 'myPermission',
  redirectTo: /* @ngInject */ function($myService, transitionProperties, rejectedPromise) {
     ....
  }
}

To make backwards compatible, you could detect if the function is setup for strictDi (either being an array with trailing function value, or a function with a $inject property) and either invoke directly or through the $injector. This would just enforce that injected functions must be strictly invoked.
