Missing empty section check

[gzalo]

Hi. There is a bug in this line:

If any other anchor changes the hash of the URL to one name that doesn't exist in the sectionAnchor array, the page will scroll to the first section!

pagePiling.js/jquery.pagepiling.js

Line 471 in 4f3de9c

scrollPage(section);

I think that a check like this is missing:

if(section.length>0){
 scrollPage(section);
}

Thanks,
Gonzalo
