Support for sniproxy

[LionsAd]

I think it would be better to support https://github.com/dlundquist/sniproxy instead of haproxy, because sniproxy can do wildcards, which are needed for e.g. Amazon Instant Video now as it checks region for .*\.eu\.api\.amazonvideo.com.

Also the configuration for sniproxy is very straightforward.

The current rules for Amazon translated to sniproxy are as simple as:

table hosts {
  atv-ps-eu\.amazon\.com$	*
  atv-ext-eu\.amazon\.com$	*
  atv-eu\.amazon\.com$	*
  .*\.eu\.api\.amazonvideo.com$	*
}
