Some Doctable updates.

[Pat Costello <Patrick Costello Sun COM>]

I have made the following changes to the Doctable: 

- Added Aaron Weber as one of the maintainers of the Evolution User Guide.

- Moved Show Desktop Button from the Applets section to the Control Center 
section. Eugene will cover this topic in the User Guide. 

- Removed Power Manager Applet from the Applets section. This was a Sun-specific 
applet that is now on hold.
