Scrolls

I've implemented scrolls:


They basically work like they do in most other roguelikes.

I've implemented the following types to begin with:

• Enchant Armour - enchants a random piece of worn armour with greater AC.
• Enchant Weapon - enchants a randon wielded item with either greater +hit or extra damage.
• Remove Curse - removes curses from carried and wielded/worn items.
• Teleportation - instantly teleports to another point on the level (as in the screenshot).
• Identify - identifies all carried items.
• Magic Mapping - gives knowledge of the current level.
• Forgetfulness - the opposite of Magic Mapping; takes away knowledge of the current level.
• Blank Piece of Paper - the old favourite!
• Cursing - curses a random worn/wielded item.

The enchant and identify scrolls I'll change at a later date to target only one item as they're currently much too powerful; and its also currently possible to get a magic item for free by cursing and then uncursing a common-quality item.

I've uploaded the changes to the repository.
