using block for dismiss camera modal window.

sometimes I want to bring up another modal window after the imagepicker window is dismissed, such as a picture editor modal window. It fails because it cannot bring a new modal window when the imagepicker window is in the process of getting dismissed. 

so i update the CDVCamera code to use block, like following. 

[[cameraPicker presentingViewController] dismissViewControllerAnimated:YES
                                                                      completion:^{
                                                                        [self processPickedImage:cameraPicker didFinishPickingMediaWithInfo:info];
                                                                      }];

please let me know your thoughts. 

Thank you
