STORM-1021 FIXED Viewer shows "L$300" instead of object IM details if object sends an IM from another region.

The problem was caused by trying to lookup info for a *remote* object by its id in the gObjectList --
this is what the usual object inspector (LLInspectObject) does.

The fix saves the sender object info when a message arrives, then passes the info to the remote object inspector (LLInspectRemoteObject).
