From cffd73c59fb8cba3b93a1555173e3f4d5cda1258 Mon Sep 17 00:00:00 2001
From: Melanie Thielker

Subject: Reintroduces the discovery mechanism to use
 llRequestSimulatorData("", 128) Causes the dataserver event to return
 "OpenSim" when running on OpenSim. Requires ThreatLevel to be "High" or above
 to function.
