pretty much finished the basic wiki capability today

Renamed the roles command to be names, as it lists all the accessible named rolons.

But the big news is that the cit command is now working. This command lists all the rolons which have a reference to it. And this completes the basic wiki capabilities. This is a bit tricky, as a reference can either be by name, relative pathname or absolute path name. And since names are not unique, references to the current context only count if they actually resolve to the current context. (The first time I implemented this logic, several years ago, it was a lot more than just one day's effort. This time it was a snap, and a whole lot faster than any of the previous implementations. But then, this is one of the features that the database was designed to handle.)

Now my attention turns to database utilities, reliability and the like. And then we move to beta and start working on all the advanced features. Finally!
