Store scope along with registered functions

[christoph]

I have added a simple yet crucial detail to the JavaScript class MapbenderEvent.

Now you can register a function along with the scope it's going to be triggered in. You simple pass the scope as a second parameter to MapbenderEvent (a stupid example follows)

var obscureClass = function () {
     this.obscureVar = 42
     someEvent.register(function () {
        alert(this.obscureVar);
     }, this);
 }

if someEvent is triggered, the correct value 42 is displayed. Please let me know if you have any questions.
