Implemented some simple 'enemies' and action log.

I put myself a severe restriction for screen real estate, to force me to be creative. The challenge is that as I get more tired, my code gets sloppier (which in turn required I spend more energy to do anything) and my imagination fades...

I got to say, I'm starting to get a bit worried about time. There's so much to do! Items, Level system, Balancing... But I'll keep pushing until I have something worth sharing!
