Fix [Github] rate limits in CI

Alternate to #1094 for fixing #979.

Looks like a good approach,
From the looks of github-auth.js, the keys are stored in /private/github-user-tokens.json as something along the lines of:

{
  "data" : [
    "yourkeyhere",
    "asecondkeyhere",
    "athirdkeyifneeded"
  ]
}

although i may be wrong as i haven't actually tested it all out

edit: never mind, looks like you can store it in either file, i missed this line,
Makes sense to just store it in /private/secret.json as only 1 key should be needed.

Cool. It's working, by the way! The CI build on this PR is running all the Github tests. I'm eager to get this fixed. I guess I was hoping for a better solution than this, though clearly I should have just done this a long time ago.

@Daniel15, would you mind reviewing this?
