Missing Option: Alert keep active while MouseOver

[asfixia]

Expected behavior

Should have a parameter what allows the user to keep the alert while the user is with his mouse over.

Suggestion to implementation:

Two new functions:

var isDescendant: function (parent, child) {
    var node = child.parentNode;
    while (node != null) {
        if (node == parent) {
            return true;
        }
        node = node.parentNode;
    }
    return false;
}

var hideElementAfterMouseOver = function(elem, alertConf) {

  if (!elem) {
    return;
  }

  if (alertConf.target && !isDescendant(elem, alertConf.target)) {
    window.removeEventListener("mousemove", alertConf.mousemove);
    alertConf = undefined;
    hideElement(elem);
  } else {
    setTimeout(function() {hideElementAfterMouseOver(elem, alertConf);}, 200);
  }
};

Modify the function 'close':

close: function(elem, wait) {
    if (this.closeLogOnClick) {
        elem.addEventListener("click", function() {
            hideElement(elem);
        });
    }

    wait = wait && !isNaN(+wait) ? +wait : this.delay;

    if (wait < 0) {
        hideElement(elem);
    } else if(wait > 0 && !this.stayWhileMouseOver) {
        setTimeout(function () {
            hideElement(elem);
        }, wait);
    } else if (wait > 0) {
        var alertConf = {
            target: null,
            mousemove: function (evt) {
                alertConf.target = evt.target;
            }
        };
        ExtjsUtils.addDomListener(window, "mousemove", alertConf.mousemove);
        setTimeout(function () {
            hideElementAfterMouseOver(elem, alertConf);
        }, wait);
    }

},

And add a property "stayWhileMouseOver" to the _alertify object.
