	There is one actual behavior change here, in the webidl version of TreeBoxObject::GetCellAt. I believe this change fixes a leak of the nsTreeColumn, but could use careful review. I tried to avoid changes not needed to get this compiling. There will be a lot more cleanup in the next few changesets.
