Add Monster Races for B&T

[nonplayer]

Add an "extended races" option for B&T and other game which allow further racial selections. B&T has monster race options, might as well allow those as well.

I'm considering adding an "extended" flag to the CLI arguments for this. -X or such. This would have an extended set of options for the games, such as "advanced" rules sets or such. If used, and if the game supports it, it would activate those options within the generator.

Probably easier to add "bntx" as a selectable game option that is just bnt but with extended races (monster races from core). Then perhaps "bntxm" also adds the monster races from the monster book, too.

Added "bntx" and cleaned up some logic. Tested with two new races (aasimar and automaton). Tests look solid so far, moving forward with the rest of the monster races from the core book.

I've added:

• Aasimar
• Automaton
• Azer
• Drow
• Goblin
• Kobold

The list is quite massive, though. I'm calling this done for now. If anyone wants a new race added, submit a PR, or just ask for it.

Ugh, scratch that. I need to combine the bntx races with the bnt races somehow...

Just gotta merge the race_choices and race_data from bnt. Hmmm, might need to separate each out as its own dict...

[nonplayer]

Well that was easy enough. Closing again!
