run-headless: Disable cross origin protection ("webSecurity")

[allquixotic]

This is required to support the latest release of PhantomJS.

Explanation and 1-line diff here.

PhantomJS 2.1.1 is now properly respecting cross-origin strictness with web-security set to true (the default). To maintain support for the way the bot is architected, we have to tell PhantomJS it's okay to do cross-origin stuff. We trust chat.SE/SO and the bot script, right? :)

NB: PhantomJS 2.0 erroneously allowed our cross-origin stuff to run just fine with web-security enabled. This was actually a security vulnerability of sorts in PhantomJS. So we're just regressing our "security level" to where we used to be, not actually making it any worse.

What part of the bot violates web security?

[allquixotic]

Hmm, not sure. PJS doesn't give me enough info. I can try to find out exactly what it is, but would probably need a verbose option somewhere in Nightmare.

Here's the console output with webSecurity enabled (no errors with webSecurity false):

$ node run-headless.js
phantom stdout: NETWORK_ERR: XMLHttpRequest Exception 101: A network error occurred in synchronous requests.

Update: With PhantomJS --debug=true, not much better output (squelched notification of my cookies being picked up from the CookieJar):
