Please add th possibility to add attributes to first, prev, next and last links

[gubi]

I would like to add tooltip class but currently is not possible with your code.
Please add a feature to add custom attributes to pagination buttons.
The insterested code is in lines 135~152 and , for example, could be as follow:

            if(settings.firstLastUse){
                p = p.concat(['<li data-lp="1" class="', settings.firstClass,
                       '"><a href="', href(1), '" class="', settings.firstLastClass, '" title="', settings.firstLastTitle, '">', settings.first, '</a></li>']);
            }
            if(settings.prev){
                p = p.concat(['<li data-lp="1" class="', settings.prevClass,
                       '"><a href="', href(1), '" class="', settings.prevClass, '" title="', settings.prevTitle, '">', settings.prev, '</a></li>']);
            }
            for(var c = 1; c <= Math.min(settings.total, settings.maxVisible); c++){
                p = p.concat(['<li data-lp="', c, '"><a href="', href(c), '">', c, '</a></li>']);
            }
            if(settings.next){
                lp = settings.leaps && settings.total > settings.maxVisible
                    ? Math.min(settings.maxVisible + 1, settings.total) : 2;
                p = p.concat(['<li data-lp="', lp, '" class="',
                             settings.nextClass, '"><a href="', href(lp),
                             '" class="', settings.nextClass, '" title="', settings.nextTitle, '">', settings.next, '</a></li>']);
}
