For one thing, I think I've fixed the seg fault in E-MoonClock.  Here's
hoping.

I also added the background setting functionality to E-Slides, but this time
it was done *right*. :-)  Take a look and see for yourself.  If you look at
the code, it also demonstrates how to use E IPC to set backgrounds.

I am currently using E-ScreenSave as my test epplet for this code, as I know
only about 2 people use it ;) Try it to see the code working.
