Title: Allows setting the thumb 'Highlighted' color

Thumb image did not maintain FlatUI color when sliding 'Highlighted'

Here's an extended UISlider+FlatUI to allow for different thumbColor when highlighted/'sliding' .. this also handles the case if you use the same color for Normal and Highlighted

-- By the way, great project thanks for sharing.
