Add more git options + hub support

[Raynos]

• added a --help cli arg for printing usage
• made init-repo.js more configurable for git workflows
• allow creating a repo using hub instead of lib/create-repo.js
• add a --no-create option to only do init-repo.js and not creating github remote
• refactored test runner to be node + tap-spec instead of tap. I can change that to tap-dot instead if wanted.

This solves https://github.com/thlorenz/gitify/issues/1

I want to get the git init-repo.js flow double checked by a coworker before this is ready for merge.

[Raynos]

I tried to make the commits atomic.

This change is probably easier to review commit by commit.

@thlorenz fixed a bug and added a --set-upstream flag.

This is ready for review / merge at this point :)

Cool, will have a look and merge this tomorrow at the latest, thanks.

I merged this into options-hub branch, tests pass and all seems well. Unfortunately when trying this I got an error telling me repo exists already (although foo is not a repo I own already) - see below.

So things to do before merging into master:

• make it work (solve the issue I mentioned)
• add documentation for added features (both for API and cli usage) to readme

~/dev/js/projects/tmp/foo
➝  gitify
loaded config from:  /Users/thlorenz/.config/gitify.js
{ err:
   { message: 'Validation Failed',
     documentation_url: 'https://developer.github.com/v3/repos/#create',
     errors: [ [Object] ] },
  statusCode: 422 }
[ { resource: 'Repository',
    code: 'custom',
    field: 'name',
    message: 'name already exists on this account' } ]

I also cannot run your example:

Even if turning of hub always, I still get:

loaded config from:  /Users/thlorenz/.config/gitify.js

events.js:72
        throw er; // Unhandled 'error' event
              ^
Error: spawn ENOENT
    at errnoException (child_process.js:988:11)
    at Process.ChildProcess._handle.onexit (child_process.js:779:34)

shell returned 8

[thlorenz]

Somehow though your example still created a repo, but still errored as I showed above.

However my example still works. But the cli seems hosed somehow.

[thlorenz]

Hey any news on this? Do you still need this merged (after it's fixed)?

[Raynos]

@thlorenz we have an internal copy paste in one of our projects, we'll open source it eventually.

Once we get to that point I'll make a fresh PR into gitify since it's diverged.

I'll also write better tests :)

[thlorenz]

Cool sounds good. Thanks.
