I moved the menu items for setting color and font to a new config dialog.
There will come some more options before KDE 4.3.
And since color and font are long-term options, which does not need to be changed very often, it is a good place to stay in a config dialog.

But now you cannot see the change of the background color when you are choosing a color in the color dialog anymore.
I will address this issue in the future.
