This patch renews the System Settings -> Desktop Behaviour -> Workspace. Basically it is rewritten in QML, ConfigModule. Also, its naming is changed. It was called as kcm_workspaceoptions and workspaceoptions before and now, it is kcm_workspace like other renewed KCMs.
Currently, ToolTip and VisualFeedback working fine. All the functionalities are tested. Other than that, "Reset", "Help" and "Default" buttons doesn't work properly.
Installing this patch directly duplicates the "Workspace" because new naming. This problem should be solved.
