New Sock Counting Function, Alabaster Implemented

* New function: countCockSocks() to get the number of a type of cock
sock on the player. Opens all kinds of stackable cock sock effect
goodness
* Alabaster Cock sock implemented. It now reduces corruption by an
additional 1 for each Alabaster you have on.
* As always, code cleaning: Removed obsolete workaround and comments,
corrected some comments
