Battle tweaks; per-scene instructions text; Story.txt
Battle scenes A) now respect player armor and B) can be set to have certain odds of the enemy using magical or non-magical attacks, using the enemy's armor (0 = no magic, 1 = all magic,  0.5 = 50% chance of either).  Changing scenes now updates the instructions text to be more relevant to what the player needs to know at any time.  Wrote out a draft of the story for the full game (loosely based off of the demo story as it is now).
