Modified scrollTo method to accept relative positions: +9 or +9% for example
When the container div was sized to 0 high, the contents would "jump" position upward due to some math stuff. The limit checks were
reversed, <= instead of < and >= instead of >
Added a method 'pause', it's a copy of disable except it doesn't hide the scrollbars. I use it for resizing things without continuously
updating (and therefore causing lag).
Honestly forget why I had to do this, but it prevented some graphical problem.
