Subject: Fix failure to teleport when an agent is lured on the same sim (and
 probably in neighbouring sims) with HG lure active

It turns out that the HG lure module was setting up a pending lure when it intercepted the instant message on its way out to the target avatar.
However, an IM would only be sent if the user was remote, so it would not be set up for users on the same sim or in an immediate neighbour.
We fix this by adding the pending lure when the message goes out and ignoring a duplicate pending lure add if it goes to out via IM.
Hopefully addresses http://opensimulator.org/mantis/view.php?id=5690
