v1.1

This slightly new version which entailed working on the game for a total of ~3 hours today includes:

- Skeletons now damageable while stunned

- Various audio for fireball/arrow/oozeballs

- Better written and more appropriate text

- Updated book visuals which look much less disgusting

- Mini-map now fills itself out when walls/enemies are discovered instead of starting off filled

- Mini-map background and walls changed colours for better readability

- Fixed a bug where casting a fireball immediately against a wall caused a crash
