Defect in CCTimer callback update

[genevictor]

Sorry if this is not the best way/place to report. I do not know how to branch/commit.

In CCTimer.java:

public void update(float dt) {
    if (elapsed == -1) {
        elapsed = 0;
    } else {
        elapsed += dt;
    }
    if (elapsed >= interval) {
        if(callback != null) {
            //callback.update(dt); // original
            callback.update(elapsed); // fixed
        } else {
            try {
                invocation.invoke(target, elapsed);
            } catch (Exception e) {
                e.printStackTrace();
            }               
        }
        elapsed = 0;
    }
}
