Subject: fix the performance problems with the torrent add dialog on torrents
 with many files/dirs. the parent size updates just walks up parents rather
 than a full foreach, and the inserts try to use the previous update to speed
 up finding/creating the directories. I'll probably do something similar to
 the main files treeview.
