* Implemented BOutlineListView::FullListSortItems() and SortItemsUnder() - dunno

what Be's implementation did wrong but instead of taking almost 30 seconds to sort the MIME type database (roughly 1100 entries, and yes, that's why the original FileTypes is that slow when it has to show the internal types), this one needs only 4 ms for the same task (that's an amply 7500x speedup). * Implemented some more missing functions - it's by no means complete yet, though. * Rewrote OutlineListView.h, ListItem.h, and StringItem.h. * Fixed some minor bugs, but there are probably a lot more. * Major cleanup. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@16349 a95241bf-73f2-0310-859d-f6bbb57e9c96
