Support renamed packages.

When aapt's --rename-manifest-package option is used, the app's resources are not placed under the same package as Context.getPackageName(). I haven't figured out a way to discover the available packages that could contain resources so that we could perform a search. Instead, I provided a global variable consumers can use to tell us their resource package name.

This fixes stack traces like this:
