Add Proxy support

[dudleycarr]

Be able to specify a proxy server to use along with cookies, user agent, etc.

sure thing, sounds like an obvious thing to add.

Haven't produced binaries for it yet, but when the next npm package goes out, I will. Basic use would be like this:

var chimera = new Chimera({proxy: {
                 type: "socks", 
                 port: 1080, 
                 host: "mysocks.server.com", 
                 username: "myuser", 
                 password: "mypass"}});

You can also change proxies midway through your code by doing something like this:

chimera.setProxy("socks", "mysocks.server.com", 1080, "myuser", "mypassword");

The type of proxy can either be "socks" or "http".

Awesome! Thanks. I'll try it out shortly.

Do you know when the next binary will go out? Or instructions on how to build them? I need proxy support
