Subject: Added BUGDIR_TYPE_MOD and BUGDIR_TYPE_REM to libbe.diff.

Now you can subscribe to only hear about modified bugs or only about
removed bugs.  Kindof odd for a general subscription, but possibly
useful as an argument to the upcoming `be diff --subscribe`, e.g.
  be diff --subscribe DIR:mod
which would replace the old
  be diff --modified
