* Use KRadioAction:s + a "no zoom" -item" instead of KToggleAction:s for the zoom menu.

* Don't lose the color settings in the functions if you set a new default color.
* Use the inverted color of the background for the "Fadenkreuz" so you always can see it.
* You can choose if you want to print with transparent background or not.
* Make the file-loading work again for both new and old Kmplot-files.
* When a zoom mode is enabled: use a different mouse cursor.
* Removed some old uncommented code in KPrinterDlg and renamed kcfg_printHeaderTable to printHeaderTable to prevent confusion with KConfig XT.
