Update Camera.js

Platform: iOS
Plugin: org.apache.cordova.camera
Hardware: iphone 5
Strange behavior when selecting photos from library with camera.getPicture and cameraOptions with sourceType of Camera.PictureSourceType.PHOTOLIBRARY.
Some photos rotate in unintuitive ways. I found that defaulting

 correctOrientation to true in my cameraOptions argument fixed this problem.
