Subject: [PATCH] Use HTTPS for Google Books Images

The API for Google Books will return HTTP image URLs when matiching any
books using it as a search provider. In a secure environment, this
causes browser warnings.

All Google image links support HTTPS and we can safely switch to HTTOS
to avoid these warnings.
