Game Mechanics: Memorizing and scribing spells should be based on meditate skill

[falkun]

Memming higher level spells takes longer than memming lower level spells, so memorization (adding spells from book to cast bar) seems ok-ish.

However, scribing a spell to the spell book for the first time is WAY off. It takes me longer to memorize a new spell than it does to scribe a new spell. Memorization should be quicker than scribing, but I don't have any hard data as evidence.
