Seperate SvxBackgroundColorItem from SvxColorItem

SvxBackgroundColorItem derivated from SfxPoolItem instead of
SvxColorItem.

Casting is common usage to control if object is this or not.
When we can cast SvxBackgroundColorItem to SvxColorItem we can not
seperate them anymore.

eg: Char color is a SvxColorItem and char background color is a
SvxBackgroundColorItem. They can be hold together and we should
understand they are different types.
