The notion of a "Server Root" has gone away in Admin Server, so the Directory
Server Console needs to adjust for this.  The server root is mainly used for
setting default paths for things such as logs, databases, changelogs, ldifs, and
backups.

The attached changes remove all traces of the server root.  This was largely
done by adding some path fetching helper functions to the DSUtil class.  These
functions query the directory server configuration for the path locations.  

Another area that needed some changes was the log viewer panel.  The viewlog CGI
has changed in AdminServer, so we needed to change the parameters that we pass
to it from the console.

There are some other minor changes that I made such as popping up an error
dialog if you try to browse for an entry distribution plugin when running
console on a remote machine. I've also bumped the version up to 1.1.0.
