[PATCH] Add support to lightdm lock screen tool

[Adam Glover]

FWIW, I use light-locker, and it has the same --lock option that 
gnome-screensaver-command uses.  If you work without gnome-screensaver 
installed, then you can do what I do, which is make a symlink to 
light-locker-command.  It avoids having to worry changing the script 
every time you update the package (assuming the use of distro packages).

I'm reading a bit on dm-tool (I hadn't noticed its existence before 
now), and it looks to me like it uses dbus to send commands to the 
session manager, which must be configured for a locker. This is 
generating security complaints for cases where the user doesn't have one 
installed or configured (technically the user/admin's fault).  
Personally, I find it easier to just skip all that and work with the 
existing xflock script, which calls the commands directly (and I shim in 
the program I actually want to use like above).
