Adds a new feed type for the mastodon notification stream, which reuses most of the structure for the regular mastodon feed type (it just calls a different mastodon API method and has different logic to extract entry fields based on the response).
Also makes some cleanup of db fields.
Note that the style of the notification entries is not entirely consistent with notifications from other services (Goodreads, Github). These will likely be revisited in another PR.
