This patch makes llAllowInventoryDrop work with the permissions module
enabled. Changes include:

- Enabled PropagatePermissions when permissions module serverside perms
  is on

- change ownership of item when item is dropped into an object.
  Ownership changes to the owner of the object the item is dropped into

- propagation of permissions if the permissions module enabled (eg
  next-owner mask applied)

- CHANGED_ALLOWED_DROP is now passed to the change script event if an
  item was allowed to be dropped into the object only because
  llAllowInventoryDrop is enabled (instead of CHANGED_INVENTORY being
  passed).

- Sets object flags correctly when llAllowInventoryDrop is called so
  clients are notified immediately of the change in state. Am not
  sure that calling aggregateScriptEvents is the right way to do it,
  but it works and seems to be the only way without making further
  changes to update LocalFlags
