Debugger: Do setParent(0) on disabled dock widgets

Browse Source 
When disabling a dock widget, we don't want it to show up in the Views
menu anymore and we don't want it to interfere with other views.
setParent(0) accomplishes this. However, when showing a different
perspective we need to properly parent all the widgets that belong to
it.
