New features!

+ Increased the map size a little bit because the map generator was having trouble connecting all the rooms on a map size so small.

+ Added spell casting/scrolls -- when using a scroll, it *should* simply target the closest enemy to you. There is no manual targeting...yet. BE CAREFUL, however, using a scroll when no enemies are present will cause the spell to fizzle and the scroll will be destroyed.

+ Chests now have a tiny percent chance of dropping a scroll instead of a potion.

+ Player object now tracks sight of monsters that enter and exit the field of vision.

My best score so far is like 360 on depth 12. Try to beat it and gimme some feedback, please.
