Fluid width & scrollbar bug. 

I use unslider with a fluid width and varying height images. It is one of the few sliders that handled this well, until I had an initial image which increased the height just enough to enable the scrollbar. This reduces the page width, but the scroller container does not resize.

To fix this, I forced your `window.resize` function to run on load. This resets the width correctly.

Thanks for the plugin!
