Increased power of Scroll of Fire

Scroll of fire damage scales with your level, starting with level 3.

Also changed how blessed and cursed behave.

If you are not fire resistant, blessed scrolls do small amounts of damage. If you DO have fire resistance, they do large amounts of damage. The reverse is true for cursed scrolls.

BUGFIX: Fixes a bug in the code that governs a polymorphed player casting monster spells. The first version only worked if the monster's spellcasting attack was its second attack. The Gnomish Wizard, for example, has that attack as its first attack.

Also enables player casting of the monster spell "Summon Sphere"
