More monsters, more encounters!

I've put this as a minor bugfix, because most of the work is in a new dungeon biome that's for patreons, but this fixes the problem that the mace uses the descriptions meant for the short sword, and adds a minor plot or two to the main game, along with a couple of improvements.

I've realised I really need to get mouseover text on monsters, which shouldn't be hard, but as the possibility for more mixed-enemy fights opens up it's important you can mouse over and get "troll" or "tentacled monster" or "just some kind of unethical dude"

On with more main plotline stuff, alongside adding some work on side plots etc etc
