Title: Backup feed list using the Android Backup API

This adds backup and restore of the feed subscriptions (ref. issue #379)

The code backs up the OPML file (not the database) so that we don't need to worry about database versions. The feed list is restored when the app is first started after a fresh install. I added a minimal amount of UI: a simple Toast message showing if the restore was successful.
