Description of problem:
  On the Resource Monitor tab, there are three color wells to
customize the colors for "Used CPU", "Used memory" and "Used swap." 
Changes to these colors (1) do not update the graph on the current
run, and (2) do not save/restore themselves correctly for future runs.

Version-Release number of selected component (if applicable):
  $ rpm -qf `which gnome-system-monitor`
  gnome-system-monitor-2.4.0-1

Steps to Reproduce:
1.  Run gnome-system-monitor.
2.  View the Resource Monitor tab.
3.  Customize the colors.  Note the graphs do not change from red,
red, green initial defaults.
4.  Close the app and run it again.  Note all graphs have been set to
a black color.
  
Actual results:
  Graphs do not change immediately, and new colors are not saved.

Expected results:
  Graphs should change immediately (if possible).
  New colors should be saved and restored for future runs.

Additional info:
  I could not find any mention of gnome-system-monitor in the gconf
editor; this seems unusual for a gnome application.
