This CL adds two fields to Android crash reports. Specifically:
1. custom_themes: Whether or not the user has apps installed for using
custom themes. This should help debug obscure resources related
crashes.
2. resources_version: The product version as stored in resources.arsc.
This should help us detect if we tried to load resources from the old
apk during an update.
