Station application needs sudo for shutdown #21

Shutdown requires the entire application run as sudo. It would be nice if this 
wasn't needed.

You can add the user you want to be able to run shutdown by adding a line to 
the /etc/sudoers file like this (for user "pi"):

pi ALL=(ALL) NOPASSWD: /sbin/shutdown

This should allow the user pi to run "sudo shutdown" without entering a 
password.  I believe this syntax is correct, but I have not tested it.

This won't work as-is. The connection.py file currently has the following code 
to shut down:

    sys_bus = dbus.SystemBus()
    ck_srv = sys_bus.get_object('org.freedesktop.ConsoleKit',
                                '/org/freedesktop/ConsoleKit/Manager')
    ck_iface = dbus.Interface(ck_srv,
                              'org.freedesktop.ConsoleKit.Manager')
    stop_method = ck_iface.get_dbus_method("Stop")
    stop_method()

I can't remember right now why I did this instead of running /sbin/shutdown. 
I'll see if I can recall over the next few days; otherwise, I can modify the 
code to run /sbin/shutdown and modify /etc/sudoers as described.
