Reordering of the trac pages

[Philip Van Hoof <spam pvanhoof be>]

I reordered the trac pages a little bit and added so-called "unfinished
subjects".

If somebody is interested, make a wiki page for such an unfinished
subject and let it link on the main page.

Also feel free to "invent" your own tutorials, of course.
