TBB 3.5 doesn't allow multiple socksport lines in torrc because it uses deprecated sockslistenaddress in torrc-defaults
If I manually edit Data/Tor/torrc in TBB3.5 to say
socksport 9150 socksport 9160
then my TBB fails to start Tor, because Tor says
Dec 20 00:49:47.169 [warn] SocksListenAddress can't be used when there are multiple SocksPort lines Dec 20 00:49:47.169 [warn] Failed to parse/validate config: Invalid SocksPort/SocksListenAddress configuration
The man page says SocksListenAddress is deprecated as of 0.2.3.x-alpha.
I think we should simply remove that sockslistenaddress line from torrc-defaults.
