Subject: Add AllowRegionRestartFromClient setting to [EstateManagement]
 section of OpenSim.ini.

Setting this to false will block all restart requests from the viewer even if they are otherwise legitimate.
One use is to block region restarts if necessary whilst restart functionality remains buggy or triggers bugs in modules,
though these should be fixed as soon as practicable.
Default is true, as has been the case historically.
