7DRL Day 3

Day 3 is done!

New features:

• Rogue AI that decides between surviving, improving equipment, attacking, looting, exploring, trying items, and the fallback skip turn.  Currently a simple navigation behavior and the fallback are implemented.
• Conjurer team monsters now spawn!  Currently only Kestrels (k)
• Movement commands now contextualize into move, prod neutral/friendly creature to move (they don't, yet), or attack enemy (attack doesn't actually occur).
• Lots of bugs fixed and surely introduced.
