Counting points from user not DRY

[GSoster]

Right now the code below is duplicated on client/view/user/user.js and client/view/home/timeline/timeline.js

var points =  Points.listPointsFromUser(Meteor.userId());
    var totalPoints = 0;
    points.map(function(x){totalPoints += x.points;});
    return totalPoints;

A file with frequent functions should be created and this code should be put there.
