Add Advanced Zim Crafter books to Tradeskill Researcher

Similar to how we can research our class-specific tradeskill recipe books, it would definitely help give tradeskillers *more* to research beyond house items at this point (as much as I love them ) in the xpac. The tradeskill daily gives us many patterns to work with, but there aren't many ways for crafters who don't run heroics to make use of these beyond selling the patterns.

It would be nice to be able to research the Advanced Zimaran Crafter books, even if they were at an inflated status cost as compared to the class-specific ones.
