Option of scrollbar out of content

I added the option 'barHolder' to put the scrollbar out of the div with the content that is scrolled. You can pass a div positioned anywhere (even absolutely positioned ones) and the scrollbar will be placed there. It will have the same height as the container with the content being scrolled.

Added an example as well (even though it might break if someone adds an example before).

Didn't minify, please let me know which tool you use and I'll do it.
