Removing some folder customization options

Browse Source 
The old folder preview and animation relied on creating bitmaps for transition.
As we move to hardware bitmaps, creating custom bitmaps which rely on icon bitmaps
would be costly (hardware bitmaps are immutable and cannot be drawn on a software canvas).
