SynthDescLib:send flag to decide whether or not to send descs loaded from disk
Also cleaning up "targetServers" --
1. It would never have worked anyway. If you didn't pass in aServer, then
targetServers would have been set to a literal array equivalent to [\aServer]
-- and when you send to that, it would break.
2. But, we never noticed that problem because targetServers was assigned
but then never used.
So I just removed that bit and replaced it with a "x ? y" expression.
