Here is V3 as promised. A new feature and new icons

What is the new feature? "Screen Lock" is the new feature.
It allows you to quickly lock your session when need be.
This option will only be visible in the dialog if you have any one of the following installed,
lightdm
suckless-tools
i3lock
light-locker
xscreensaver
The script will prefer the "Screen Lock" helper application in the above order.
If none of the above is installed the "Screen Lock" button won't appear in the dialog menu.
I have decided to rename the script to "vs-session-manager" to avoid any conflict with the current "vsido-exit" script.
So here is how to install V3,
Download the attached
vs-session-manager.tar.gz archive. Extract its contents into a directory.
Open that directory in terminal emulator.
Run the following commands,
sudo cp vs-session-manager /usr/local/bin/
sudo chmod 755 /usr/local/bin/vs-session-manager
sudo cp vs-session-manager.desktop /usr/share/applications/
sudo chmod 644 /usr/share/applications/vs-session-manager.desktop
sudo cp logout_exit.png logout_lock.png logout_reboot.png logout_shutdown.png logout_suspend.png vs-session-manager.svg /usr/share/pixmaps/
You can manually add an entry for "vs-session-manager" in Fluxbox menu.
It will autometically show as "vs-session-manager" in the main menu of any freedesktop.org compliant DE or WM.
Feedback welcome

Here is a scrot of "vs-session-manager" in action,
Cheers!!!
