Add Improved Window Management Support

When we click into the CheckBox the following effects are being enabled:

*kwin4_effect_desktopgrid
*kwin4_effect_presntwindows
*kwin4_effect_dialogparent

If one of the above effects gets disabled, then the checkbox is unchecked.
Our CheckBox can detect if our effects are enable at the start time.
