Roguelike Action Card work

I added some basic action cards to the interface just in time for August’s monthly build, but you couldn’t really do anything *with* them – action use was still using the temporary UI. So today I spent a little time making it so you can fan through available action cards and select one.

Executing the action is still done with the keyboard or temp UI, but I’m planning to make it so you can click on stuff on the board soon. The game ~should~ be playable with just the mouse if all goes well 🙂
