[Suggestion] Discovered / created N'Zoth, Hadronox etc

[Seminko]

I had an arena game where I discovered / created Hadronox. I was anticipating the overlay to appear but it didn't. Not sure how the plugin is set up since I haven't looked at your code but that might be a cool feature to implement where the plugin would grab the game stats regardless of whether you have cards like N'Zoth / Hadronox etc in your deck and having the overlay appear if you discover / create one of them.

I'm quite confident I had all the options enabled and had at least one deathrattle minion die, but not 100% sure since the game happened some time ago...
