Rogue Runner v0.6 - Basic AI

We've made a start on some basic move and attack AI for enemies.

At this point we've got the enemies moving and staying in the bounds of the rooms, attacking the player character if they move into it and the game deals with the room being deleted (which caused a minor hiccup).

I've sped up the enemy turns as well, just to increase the pace of the game a little.

Next is the inventory. I want to keep it quite simple for this game initially but we all know how seemingly simple things end up in game development.
