Using res-auto namespace instead of com.android.contacts.

Using "http://schemas.android.com/apk/res-auto" instead of
"http://schemas.android.com/apk/res/com.android.contacts" for custom
namespace. This will allow aapt to replace it with proper app
namespace and thus allow us to share resources between apps.
