From: Dr Scofield <hud@zurich.ibm.com>

the attached patch set is centered around RemoteAdminPlugin and focuses
mainly on making it more robust (i.e. more parameter checking and better
error reporting) but also we've re-implemented the LoadTerrain stuff that
got disabled during the terrain code reworking:

   * missing PostInitialize() calls on region modules that were loaded
     for regions created via RemoteAdmin's CreateRegion XmlRpc call
   * re-implements RemoteAdmin's LoadTerrain XmlRpc call (probably lost
     during the TerrainModule rework)
   * adds lots more parameter checking and error reporting to RemoteAdmin
   * adds a read-only property to RegionApplicationBase so that we can
     access the CommsManager
   * adds Exceptions to TerrainModule so that we get better error case
     feedback (and can report more meaningful errors in turn)
   * adds a CheckForTerrainUpdate() call to
     TerrainModule.LoadFromFile() to make terrain changes effective
   * adds TryGetCurrentScene(LLUUID) to SceneManager so that we can
     retrieve Scenes not only by name but also by LLUUID
