fix configuration file path to a more rational one

[timqi]

fix #5

[timqi]

seems no response when parse download url in checker.sh of travis-ci @Doublemine

@timqi Thanks for PR, #5 point to the conf file location can be confusion. I think migrate conf file to new dir may be better choice. Such as /usr/local/etc/v2ray/config.json. And what's your suggestions?

[Doublemine]

Pls update readme.md as well, Thx.

@timqi When i test this pr, it will cause the error: Error: No such file or directory - v2ray/config.json. And i guess below code may cause some error:

etc.install "v2ray/config.json"

Had you tested it ?

[timqi]

Sorry for that I don't know how does etc.install work. It may cuz v2ray directory in etc path doesn't created before. Please help handling this at your ease.

[Doublemine]

Maybe i guess you can try this:

def install
    bin.install "v2ray"
    bin.install "v2ctl"
    bin.install "geoip.dat"
    bin.install "geosite.dat"
    (etc/"v2ray").mkpath
    etc.install "config.json" => "v2ray/config.json"
 end

And do some improve, i have not verified whether it is work, so you should test it on your mac env.
