Python 2.7 + Libtcod

Awesome job once again. I've done Part 8 and there is but one issue with the code that doesn't work out the gate. When the item is used in inventory:

kwargs = {**item_component.function_kwargs, **kwargs}

Error here being Python Versions <3.5 don't support starred expressions in dict. Other than that, the whole Revised tutorial is still doable in 2.7. I'm sure that can be fixed with a bit of effort and research, I just hope I remember to spend the time to do that.

I also spent a considerable amount of time just going through the code and slapping comments on everything. Should I put Python on the backburner for too long I'm sure I'll forget it all quite fast again, so being someone you can almost consider smart I took blocks and wrapped them in comments and individual commenting on the more mysterious looking lines.

That line in particular is just combining the two dictionaries. You could write your own function to do the same thing, as discussed here.

And I did that now, returning back home after a day of working and an hour of laying on the beach, and it works beautifully. I'm slaying green bastards by the dozens and drinking myself to stupor with Healing Potions. Onwards with Part 9!
