* New helper function to determine a user's DISPLAY environment
* Use that function everywhere that a DISPLAY is required
* When no DISPLAY, use write(1) to notify user via tty
Added debug log option, using it for echoing commands and such low-level
stuff to the parental-time-curb.log
Try harder to detect the user's DISPLAY
Typo fix for now_opoch instead of now_epoch
debug the lock_count a little, tracking logic issues
Trap the command output for the gnome-screensaver-command call better.
Tries to reliably detect the screensaver of gnome sessions. Need to make
this support KDE and Xscreensaver at the least?
Don't hard code the source path for common.sh, use dirname instead.
Makes development easier.
