r8257: add a samr rpc test page in the web server. It lists all level3
information from QueryUserInfo for all users in the domain.

If you want to see why I am putting the effort into ejs, then please
read swat/scripting/samr.js, and compare it to other methods of rpc
access for our web management interface. Using ejs like this will make
building a rich interface _much_ easier.
