AniDB Authentication and Tag Builder

[Critical-Impact]

Description

1. config.yml has a new section for a username and password for anidb
2. the anidb builder will do an initial login and then continue using the same session
3. there is a new anidb builder called anidb_tag that lets you specify a tag id and it will paginate through the entries to build a collection

As AniDB has age gates, logging in is a requirement to use some tags, as such I've added in optional authentication. If no anidb configuration section exists in config.yml it will skip authentication and use guest credentials as it has in the past.
