[AgileWiki] admin commands checked in

[Bill la F. <bil...@su...>]

I've now completed the setDU, setCEnt, setDEnt and setLEnt commands. 
(Remember to do a build clean of AwServer after the svn up.)

These are semi-hidden commands. You must be a member of the admin group 
to use these commands AND you need to use the rolonic interface.

Using these commands, you can make low-level changes. Use them for 
configuring things with special requirements and for fixing things that 
have gone bad. But note that there are very little validation done. So 
have a care.
