Added play-fizzle-sound option to most instant spells (plays the fire extinguish sound when a spell fails to find a target)
Added consume-book option to tome spell
Added portal-animation option to blink spell
Windwalk prevents all block interaction now, which should fix most free-item issues with it
Added cancel-if-full and show-spell-effect options to heal spell
Fireball now uses damage-multiplier option instead of additional-damage
Fireball now plays casting sound
New fireball options: small-fireball (doesn't work well and fire can't be prevented), no-explosion-effect, no-explosion-damage, no-explosion-damage-range
