Add partial Hama.bundle agent support

[reconman]

I'm using the Hama agent for Anime which allows you to either fetch the metadata from TVDB or AniDB.

The GUIDs in TVDB mode look like this: com.plexapp.agents.hama://tvdb-377543/1/1?lang=en
The AniDB GUIDs look like this: com.plexapp.agents.hama://anidb-15772/1/1?lang=en.

I would propose a really simple solution which just looks for com.plexapp.agents.hama://tvdb and then treats it the same as TVDB GUIDs.

I could probably submit a PR for this topic.
