Update CN list from gfwlist

[willscott]

There's a maintained list of cn domains at
https://github.com/gfwlist/gfwlist
that would be worth interacting with, since it is used by many vpn clients to selectively proxy only blocked content.

Did you figure out what is the format of the actual list? I briefly looked at it and a-part from the base64 encoding wrapping it the actual content has some weird encoding to it.

Edit: found some possibly useful links:

• Need explanation of the data format gfwlist/gfwlist#401
• https://github.com/gfwlist/gfwlist/wiki/Syntax
• How to use this repo? gfwlist/gfwlist#3

It's the adblock plus syntax: https://adblockplus.org/filters

GFWList maintainer here, questions are welcome.

Simply speaking, GFWList is a list wrapped in base64 encoding inheriting Adblock Plus syntax with small modification.
