Categoricals: Provide separate functions for effects and dummy coding.

Until now, the function categoricals_get_code_for_case returned the
"effects" coding (ie, a bipolar code).  Some uses require "dummy" coding
(a binary coding).  This change provides seperate functions to return
whatever is desired.
