Right, i had an impression, that so much string processing going from
the need to build a tree from class category names.
But again, there is no excuse in doing this each time you need a tree.
Thanks to system notifier we have a ways to determine when category
tree needs to be rebuilt, so it can be built once and stay cached
until user add/remove/rename category.
