[PATCH] Extend xflock4 with custom screensaver application support

[Andrew Sichevoi]

Hello there!

     Currently the entry point for locking the screen for ``xfce4-session''
and ``xfce4-power-manager'' is ``xflock4'' script which is shipped with
``xfce4-session'' package.
     The script checks the list of "known" screensavers and when the first
available is found it will be launched.
     By default its knowledge is limited by the following
applications: xscreensaver, gnome-screensaver, xlock, slock. No other are
supported.
     So the only way to add support of user-preferred screensaver is to
hack ``xflock4'' contents which could be overwritten during the next update.

     Please consider the following patch to be reviewed/added.

     The patch allows to specify a custom screensaver application in XfConf
registry by the following path: xfce4-session/screenlock/command
     Please find the patch below and on Pastebin: http://pastebin.ca/2158914

     Thanks.
