Damn this is something to do with the checkbox change I made...

## TODO List

- [x] Embed the http proxy server [privoxy](http://www.privoxy.org/), [get it](https://homebrew.bintray.com/bottles/privoxy-3.0.26.sierra.bottle.tar.gz).


- [x] ACL mode support [Shadowsocks ACL](https://github.com/shadowsocksr/shadowsocksr-libev/tree/master/acl)

Appears to be the bit that kills things

FFS! I did actually test that change but then noticed the SetAttributeString and must not have properly tested again!
