Subject: [PATCH] If a window specifies flag to show even when screen is
 locked, the keyguard is hidden and conversely if the keyguard has been hidden
 its shown. this lets the window manager to hide or unhide the keyguard based
 on activities that specify if they want to be displayed inspite of the
 keyguard being shown or not.
