good progress on rewriting the Topic display

I am very close to finishing the new Topic display. Includes, names and matches are all listed together with the Topic's children. I am also happy with the transparency it is bringing to the Ark. This should help a lot in making the Ark more usable.

Now if only I could improve the UI. The top of the display is just too cluttered. Perhaps if I added some borders to visualy organize it. ;-)
