* Added B_WATCH_INTERIM_STAT, and B_STAT_INTERIM_UPDATE definitions to

NodeMonitor.h.
* The latter will be set in "statFields" for interim updates when you have
  asked to get them via the former.
* BFS now uses the B_STAT_INTERIM_UPDATE flag for sending updates to actively
  written files.
* This makes us more compatible with BeOS again; if you only asked for
  B_WATCH_STAT, you will now only receive a notification if the file in
  question has been closed.
* Tracker now uses B_WATCH_INTERIM_STAT to always get all updates (ie.
  downloading a file will update its size and modification time in Tracker
  periodically during the download).
* Wether "needsTrimming" was true or not has no influence on wether or not
  the size index needs to be updated in BFS - only the actual file size is
  stored there, not the on-disk size.
* Added a TODO comment in Inode::WriteAt() that it would actually need to
  update the size index when changing the file size, not when the file has
  been closed (but that's probably too slow).
