convert gfwlist and a ad block list to dnsmasq's config file

1. python list2dnsmasq.py

2. /
   ├── myblocklist.txt      // block list, domains
   ├── mygfwlist.txt        // user's gfwlist, same rule as gfwlist
   ├── ignore.txt           // IP or domain will be removed from all list below
   │
   ├── forward_ip_list      // config file for openwrt-shadowsocks Forward List
   ├── gfwlist.conf         // dnsmasq config file, domains will be redirected you proxy
   ├── whitelist.conf       // dnsmasq config file, domains will be directed to their server
   └── blocklist.conf       // dnsmasq config file, DNS request will be redirected to 127.0.0.1:2 by default```
   
   `gfwlist's` priority is higher than `whitelist's`
