dgui: fix regression in DirectScrolledFrame (see #699)

Browse Source 
Made initialization ignore the setScrollBarWidth function
Respect the length/height of the scrollbar and only change the actual
width in the setScrollBarWidth function
Added a very basic unittest class for the scrolledFrame

Closes #864
