Sewer monster's portraits (Patreon)

So I've fixed up some icons for the Dire Ratling and the Kobold. These will be the turn indicators when engaging them in combat.

I've also decided to stop making big portraits for monster (the ones that appear when you scroll over a turn indicator to inspect a monster), because it's mostly a legacy thing from the time before the game was made in unity.

I can save some time by only doing icons only, and then put that time into other aspects of the game. I hope people are okay with this change.
