[4.5.1, Video and Repro Project] I had to revert to 4.3 Again, Set Simulate Skel Mesh Bug On Client

As per our talk and testing, the below code seems to be an adequate workaround to the issue at hand. Replace Mesh->SetSimulatePhysics( true ); with the following:

if( !Mesh->bEnablePhysicsOnDedicatedServer && IsRunningDedicatedServer( ) )
	return;

Mesh->BodyInstance.bSimulatePhysics = true;
Mesh->bBlendPhysics = true;

for( int32 i = 0; i < Mesh->Bodies.Num( ); i++ )
{
	Mesh->Bodies[ i ]->bSimulatePhysics = true;
	Mesh->Bodies[ i ]->UpdateInstanceSimulatePhysics( );
}

Seems that using SetInstanceSimulatePhysics on the Bodies as per 4.5 does not work for replication, where as the 4.3 method of UpdateInstanceSimulatePhysics does.
