I know, I know, it is getting nasty lately but I have another large commit after nothing but code.

This time I redid the "category"-stuff.  Categories - from now on called sections - are now maintained from the admin pages, can have their own post, dump and timout thresholds as discussed earlier (some weeks ago).  By tomorrow evening users will be able to enable or disable section as well - i.e. to customize the content of drop.org.
