Skill book focus drain rebalance

Reduce focus loss from skill books from -100 to -50.  Had this fix as
part of my studious nature perk but my total inability to get gettext to
work has essentially cut me out of development :(   I'm not going to be
able to finish studious nature, so I thought I'd just submit this by
itself.  Talked with Funnyman about this when I was still able to work
on my perk mod, and we seemed to think this value was pretty balanced
(Even Funnyman agreed the original value was WAY to high).  It worked
fine before with all my other changes, so I don't see any reason it
shouldn't work on its own.  Although for obvious reasons I can't test
it.  Well this'll probably be my last pull request so I wish you all the
best with working on this awesome game.  I'll probably still play the
experimental builds occasionally but I can't see myself trying to code
anything new since I can't test it.  So see ya chummers, G'luck in your
struggles!  (Hope someone gets this reference)
