Support GitHub Enterprise

[vermiculus]

Hopefully this fixes #1 😄

@saintaardvark, you're the only one I know of who uses GitHub enterprise (via vermiculus/magithub#34). Would you mind testing this?

You'll need to generate an OAuth token and configure it in your .authinfo (or .netrc or whatever's configured in auth-sources) to authenticate, then you can run

(let ((ghub-domain "my.domain.here"))
  (ghub-get "/issues"))

If you can, test also without the let-binding to ensure it then grabs issues from this GitHub.

Hi @vermiculus -- sorry for the delay in replying. Many thanks for this -- I'll give it a try in the next few days and get back to you!

Awesome, just let me know! I'm going to be moving Magithub to ghub 'soon' to open the doors to better integration; I'd hate for the package to break for you (and others that use Enterprise).

That said, I may still be releasing that before this is merged, but at least a patch will be available.
