Updated android-support-v4 library to a newer version

I have the facebook-android-sdk set up as a submodule in my android project and you are using an old android-support-v4 library that is missing some classes that I need e.g. android.support.v4.content.WakefulBroadcastReceiver and in order to be able to build my own app the android-support-v4 library in the facebook-android-sdk needs to be the same as the one in my own app. I would prefer to have my git submode pointing at your repository rather than a fork only containing a more up to date android-support-v4 library so it would be great if you updated the android-support-v4 library in the sdk.
