Add missing warlock grimoires from 10.2.5

[DHainzl]

10.2.5 added new customization options for the warlocks Darkglare and Demonic Tyrant pets. This PR adds these to the journal.

Additionally, I've added:

• The ability to pass in a zoneID for sources.Raid bosses, similar to how that is supported for dungeons, so users can see immediately which raid a boss is in
• Categories for the pets (which mirror the different pet types), similar to how it is set up for the different drake manuscripts. I was working on a few more changes to display these as actual headers, but I haven't found a nice way to code this in without too much refactoring yet - but I figured I can keep the data in for now as it doesn't hurt having the categories already.

Okay, this should sort them into categories. I'll give it a day or two for testing before I release it.
