Slider: Fixed min and max range sliders to add ui-slider-range-min or ui-slider-range-max class and not set corresponding left/right/top/bottom inline, only width/height

(fixes #4182 - slider min/max classes aren't being added to range div)
(fixes #3850 - Slider Range With Fixed Max Demo Bug in Opera)
