Fixed alcohol not affecting your stats at all.

Apprently, alcohol handling was using broken or outdated methods, which
resulted in none of it's effects on your stats working.
Note that alcohol is now EXTREMELY damaging to your stats compared to
what it was before (I don't even know how long this bug was around),
because the debuffs from alcohol stack on top of the debuffs from
alcohol counting as a powerful depressant. In fact, the debuffs from
depressants are more damaging than the alcohol itself: perhaps alcoholic
drinks could be given slightly higher STIM values to offset this.
