Updates the hosts file with all of the hosts given on website

The JSON list here: http://tilde.club/~pfhawkins/othertildes.json provides a (partial?) list of tilde.club servers, I wrote a little script which extracts the json and generates a valid Linux hosts file.  From the issue listed, this may be useful if AWS's DNS manager is used. The script I used to generate the file is available as a gist: https://gist.github.com/lbearl/6222e98f6e51173a69e5
