.ui-widget-header should use separate bg image

[MLukman]

Currently .ui-widget-header uses the bg_button.png image background, which is a sprite image, thus if any tall element is given this class it will look weird. Better to use separate and full (i.e. not sprite) background image to cater for tall elements. TQ

this has been fixed

didn't expect this to be fixed by removing the background img altogether .. the current white text over bluish-gray background as the color scheme for .ui-widget-header looks weird to me as the low contrast kinda de-emphasizes the 'header' element. I'd suggest black text with a hint of white shadow: color: #000; text-shadow:1px 1px 1px rgba(255,255,255,1)
