Quickened Spells

It is now possible for wizards to use their spell book to purchase cooldown reductions for their spells. Each reduction costs a spell book charge and will be properly refunded if spells are unlearned. 

The reduction will cut the original cooldown by the number of times it was bought (so a 60 second spell with three charges will have a 20 second cooldown but one with two charges will have a 30 second cooldown).

Each spell has had its maximum level for quickening set manually to prevent weirdness and try to preserve balance. These values are VERY open to discussion:

Magic Missile: one upgrade to 7.5 seconds allowed
Fireball: two upgrades to 3 seconds allowed
Disintegrate: two upgrade to 20 seconds allowed
Disable Tech: three upgrades to 10 seconds allowed
Smoke: four upgrades to 2.4 seconds allowed
Blind: four upgrades to 6 seconds allowed
Mindswap: two upgrades to 20 seconds allowed
Forcewall: four upgrades to 6 seconds allowed
Blink: four upgrades to .4 seconds allowed
Teleport: two upgrades to 20 seconds allowed
Mutate: No upgrades allowed
Ethereal Jaunt: two upgrades to 10 seconds allowed
Knock: one upgrade to 5 seconds allowed
Curse of the Horsemen: four upgrades to 3 seconds allowed
Flesh to Stone: Three upgrades to 15 seconds allowed
Summon Guns and all artifacts: not affected
