issue with dehighlightElement

[jtorbicki]

I've found a small bug in a hideAll function. Instead of this code:

line 484:

if (currentGuider && currentGuider.highlight) {
    guiders._dehighlightElement(currentGuider.highlight);
}

It should probably be something like this:

if (currentGuider && currentGuider.highlight && currentGuider.attachTo) {
    guiders._dehighlightElement(currentGuider.attachTo);
}

Otherwise this code:

guiders._dehighlightElement = function(selector) {
$(selector).removeClass('guiders_highlight');
};

Tries to remove the class from the "true" value.
