- move Shadow configuration UI to libs
- removed useDropShadow and useOxygenShadow options, and replaced by activeShadow::enable and inactiveShadow::enable
- use kcfg for decoration configuration. The handling of exceptions requires dedicated readConfig and writeConfig methods, implemented in oxygenutils
- changed sizegrip combobox into a check box and rephrased for clarification
- never draw separator
- draw separator when window is active
- always draw separator.
This is usefull for e.g. firefox, when a flat background is used, in which case one might
want the separator to always be enabled.
