a day refactoring wiki, thoughts on references

Had a good solid productive day debugging and refactoring the wiki logic.

I've also been thinking about (symbolic) references. As implemented, they will not work when page names are extended with dataset qualifiers. (E.G. {MainPage/Main}.) But that's going to take some real work, as none of the tkcs data structures are a good fit. ;-( The complication is that I need a sorted key/value list that changes over time. So I'll need to go back to the tks level and see how to implement it there, as I did with dictionaries.

Meanwhile, I need to bring the web code up to date. (I've said this before, I know.)
