Tomes

Additions:
- 1 new active and 1 new passive spell for each tome type!

- Goblet of Hearts block. Can be filled with items to create all sorts of effects.

- New boss called Witch of Cogency.
- Item dropped from Witch of Cogency called Amulet of Cogency that decreases cooldown time of spells by 50%.

- Maybe more I missed.

Changes:

- Tweaked heart drop rates.

- Hearts can be consumed.

- Coven's Rule doesn't play mean with the active spell on the tome now.

- Withering Stench now applies the Leaden Veins effect.

- Using Mind Bender on an already affected target cancels the effect.

- Repairing tomes should be fixed hopefully.

- Slight increase on the duration of the Light-Footed effect when using Self Propulsion.

- Rare spells are no longer found in chests.
- Hopefully the Linguist spell will now work with mods that affect the enchanting table, like Apotheosis.

- Maybe more I missed.
