0fb74b56b3 FIXED: CLP(B): weighted_maximum/3 with repeated variables 
Many thanks to @jburse for reporting this issue:

    https://github.com/triska/clpz/issues/15

Example:

    ?- sat(~(Y*X)), sat(Z=:=Y), weighted_maximum([7,2,5],[X,Y,Z],W).
       W = 7, Y = 0, X = 1, Z = 0
    ;  W = 7, Y = 1, X = 0, Z = 1
    ;  false.
