Subject: [PATCH] key "org.cinnamon.desktop.lockdown" consideration

related to this feature request.
#6136
I change the code for this applet just to remove the "switch user" option when the gsettings key "org.cinnamon.desktop.lockdown" "disable-user-switching" is true. I need it in Linux Mint 18.3 so I change it in this version.
